As for "in the Sahih chains Ali doesn't rebuke Hussein at all":
Well, this very Sahih narration (in the Siyar of Imam al-Dhahabi and others) is what I've posted right at the beginning of this post! I've shown how the deceitful Rafidi website (Wilayat net) cut off half of the Hadith as it is to their disadvantage. Therefore the Rafida are the last people who should speak of objectivity, haven't I proven in this very thread how Wilayat net website omitted the last part of the SAHIH narration that includes 'Omar's beautiful reaction? Of course they have to omit it as it doesn't fit with their lie that 'Omar was an Ahl al Bayt-hating/killing tyrant.
The SAHIH narration (by Imam al-Dhahabi) by Imam al-Dhahabi can be found in other books with the same Sahih chain, and despite missing the part were 'Ali rebukes his son, it contains a very important bit that destroys the entire Rafidi argument (hence their websites usually omit it):

Al-Thuqat by Al-'Ijli, chapter of "Hussein", vol. 1, p. 301, #307 with a SAHIH chain
[...] Oِn the authority of Al-Hussein (Ibn Ali Ibn Abi Talib) who said:
I went to 'Omar while he was given a sermon over the minbar (pulpit). I ascended to him and said: "Come down from the minbar of my father, and go to the minbar of your father!". 'Omar answered: "My father had no pulpit". At this time Omar got down from the minbar, and sat me on the minbar beside him and while he was descending he said: "O my son! Who taught you this?" I (Al-Hussein) said: "Nobody taught me this." He (Omar) said: "O my son, and is there anyone else besides Allah and then you (Rasulullah and Ahl Al-Bayt) who honoured us!" Then he (Omar) put his hand on Al-Hussein's head [...]
Comment: Of course they have to omit what refutes their whims, desires (of Takfir) and hatred. They have to cherry pick and leave it what stands in their way, their Majoosi grudge against 'Omar Al-Faruq, then they have the audacity to speak of deceit! Anyway, besides the fact that 'Omar treated Al-Hussein with utmost respect (and Al-Hussein was a kid, hence his statement "go to the minbar of your father", as a kid he didn't understand that 'Omar's shepherd father never had one!), notice how Al-Hussein spoiled the plot of the Rafida for ever by stating that nobody taught him what he said! Rafida are so desperate that based on assumptions claim that Al-Hussein must have heard what he said from his father ...
(http://forum.twelvershia.net/sahabah-ahlulbayt/did-al-hasan-al-hussein-rebuked-abu-bakr-omar-while-they-were-on-the-minbar/?action=dlattach;attach=1247)
... of course they have no evidence whatsoever whereas we have a clear-cut proof, a SAHIH narration by Al-Hussein himself!
In the end of the day, their whole religion is based on Mutashabihat (ambiguous text, preferably cutting verses and taking them out of context) and Thann (assumptions, like when they say that al Hassan or al Hussein must have heard it i.e. get down from my father's pulpit - from their father 'Ali the same 'Ali who made pledged Bay'ah without being forced at Abu Bakr's Shura to 'Omar!), nothing more and nothing less.
Look at their Nifaq:
The speaker in this video uses the narration in Tarikh Al-Khulafa` yet omits the bit where 'Ali REBUKES his son! If it's weak then why use it in the first place?
Listen closely how he OMITS the part where 'Ali rebukes his son:

He rambles on claiming that the little kids Al-Hassan and Al-Hussein must have learnt those statements (get off my fathers pulpit) from home, yet SAHIH narrations EXPLICITELY state otherwise. At the last few seconds of the clip he mentions Ibn Hajar Al-'Asqalani in his 'Isaba as a source, HOWEVER (AGAIN) WITHOUT reading the whole narration, why? Because the whole narration destroys his entire argument:
الإصابة في تمييز الصحابة المؤلف : أحمد بن علي بن حجر أبو الفضل العسقلاني الشافعي الناشر : دار الجيل – بيروت الطبعة الأولى ، 1412 تحقيق : علي محمد البجاوي عدد الأجزاء : 8 [ جزء 2 - صفحة 77 ] وقال يحيى بن سعيد الأنصاري عن عبيد بن حنين حدثني الحسين بن علي قال أتيت عمر وهو يخطب على المنبر فصعدت إليه فقلت انزل عن منبر أبي واذهب إلى منبر أبيك فقال عمر لم يكن لأبي منبر وأخذني فأجلسني معه أقلب حصى بيدي فلما نزل انطلق بي إلى منزله فقال لي من علمك قلت والله ما علمني أحد قال بأبي لو جعلت تغشانا قال فأتيته يوما وهو خال بمعاوية وابن عمر بالباب فرجع بن عمر فرجعت معه فلقيني بعد قلت فقال لي لم أرك قلت يا أمير المؤمنين إني جئت وأنت خال بمعاوية فرجعت مع بن عمر فقال أنت أحق بالإذن من بن عمر فإنما أنبت ما ترى في رؤوسنا الله ثم أنتم سنده صحيح ).
Al-'Isaba by Imam ibn Hajar Abu Al-Fadhl Al-'Asqalani with a SAHIH chain:
[...] I (Al-Hussein ibn 'Ali) went to 'Omar while he was given a sermon over the minbar (pulpit). I ascended to him and said: "Come down from the minbar of my father, and go to the minbar of your father!". Omar answered: "My father had no pulpit". At this time Omar got down from the minbar, and sat me on the minbar beside him and while he was descending he said: "O my son! Who taught you this?" I (Al-Hussein) said: "BY ALLAH, nobody taught me this." 'Omar said: "May my father be sacrificed for you (Arab expression for someone who hold dear) ..."
[al-Hassan] says: "On another day I went to 'Omar but he was busy with Mu'awiyah and ['Abdullah] Ibn Omar (son of Omar) was at the door, so I eventually left with him (without speaking to 'Omar). Later 'Omar met me later and asked: "Why you didn’t come?" Al-Hussein said: "O Chief of the Believers (يا أمير المؤمنين)! When I came to meet you, I saw you were busy with Mu'awiyah and Ibn 'Omar was already standing at the door (waiting to talk to his father), eventually [Ibn 'Omar left and I left with him. Upon hearing this 'Omar said: "You have more rights to see me than Ibn 'Omar, for is there anyone else besides Allah and then you (Rasulullah and Ahl Al-Bayt) who have honoured us!"
As you can see the narration actually ends with both, young Al-Hussein and 'Omar having utmost respect for each others, with al-Hussein addressing 'Omar as CHIEF OF THE BLIEVERS (Ya Amir al-Mu'minin, I guess it's now allowed to invoke 'Omar according to #ShiaLogic or maybe Al-Hussein did Taqiyyah, huh, by adding BY ALLAH ... ? Or is it an Umayyad fabrication ... there is always a Shia excuse) and 'Omar loving Al-Hussein to the extent that he gets sad that he missed seeing Al-Hussein on a random day, telling him that he prefers him over his own son!!!
What an evil evil tyrant 'Omar was ... wallahi ones love for 'Omar only increases when reading these kind of narrations. As for the Rafidah, well, they will never give up, they give entire lectures cutting and pasting bits and parts of a single narration like this one, so don't be shocked that they don't even dare to mention the complete narration, their last option is to resort to unscientifical claims such as claiming that whatever bit that contradicts with their hawa and nafs (their sect) must be fabricated. Yeah right, maybe that's a good answer for a Shi'i but a Muslim-Sunni. I thank Shias for bringing up this topic, by Allah even just reading the text quickly for the first time, my love for 'Omar and Ahl al-Bayt increased, their minds are so ill and perverted they only see evil.
PS: A very important point mentioned earlier in this thread is that unlike the shallow understanding of the Shias, Al-Hussein did not even intend his father when he said "get off my fathers pulpit". The pulpit is Rasulullah's (saws), neither 'Ali's nor 'Omar's and there are Qara'in (supportive evidence) that prove that Al-Hussein meant his grandfather:
أن المقصود بقول الحسين رضي الله عنه (منبر أبي) أي منبر النبي صلى الله عليه وسلم ، ولم يقصد منبر والده علي بن أبي طالب رضي الله عنه.
Al-Hussein's wording (get off the minbar of my father) was in regards to his grandfather Rasulullah (peace be upon him) who was like a father to him and even called Al-Hassan and Al-Hussein his sons. The Prophet (peace be upon him) referred to Al-Hassan as his son when he said, "This son of mine is a Sayyid and Almighty God will arrange peace between two groups through him." Many times the Prophet had said,"Hassan and Hussein are my children". Because of these same words Ali would say to his other children, "You are my children and Hassan and Hussein are the children of the Prophet."

And if this is not proof enough here a authentic sahih narration, with the wording JADDI (my grandfather):
جزاكم الله خيرا ، ويؤيد ما ذهبتم إليه رواية ابن شبة للأثر ، فقال (3/ 798) :
حَدَّثَنَا الْحِزَامِيُّ، قَالَ: حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، قَالَ: أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ: أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ كَعْبٍ:
" أَنَّ حُسَيْنَ بْنَ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُمَا قَامَ إِلَى عُمَرَ رَضِيَ اللَّهُ عَنْهُ وَهُوَ عَلَى مِنْبَرِ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَخْطُبُ النَّاسَ يَوْمَ الْجُمُعَةِ , فَقَالَ: انْزِلْ عَنْ مِنْبَرِ جَدِّي، فَقَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ: «تَأَخَّرْ يَا ابْنَ أَخِي» ، قَالَ: وَأَخَذَ حُسَيْنٌ بِرِدَاءِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا فَلَمْ يَزَلْ يَجْبِذُهُ وَيَقُولُ: انْزِلْ عَنْ مِنْبَرِ جَدِّي، وَتَرَدَّدَ عَلَيْهِ حَتَّى قَطَعَ خُطْبَتَهُ وَنَزَلَ عَنِ الْمِنْبَرِ، وَأَقَامَ الصَّلَاةَ، فَلَمَّا صَلَّى أَرْسَلَ إِلَى حُسَيْنٍ رَضِيَ اللَّهُ عَنْهُ فَلَمَّا جَاءَهُ قَالَ: «يَا ابْنَ أَخِي مَنْ أَمَرَكَ بِالَّذِي صَنَعْتَ؟» قَالَ حُسَيْنٌ: مَا أَمَرَنِي بِهِ أَحَدٌ، قَالَ: يَقُولُ لَهُ ذَلِكَ حُسَيْنٌ ثَلَاثَ مَرَّاتٍ، كُلَّ ذَلِكَ يَقُولُ: مَا أَمَرَنِي بِهِ أَحَدٌ، قَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ: «أَوَ لِي؟» وَلَمْ يَزِدْ عَلَى ذَلِكَ، وَحُسَيْنٌ رَضِيَ اللَّهُ عَنْهُ يَوْمَئِذٍ دُونَ الْمُحْتَلِمِ "

Al-Hussein went to Omar while he was given a sermon over the minbar (pulpit) of the Messenger of Allah (peace be upon him) on the day of Jumu'ah. He (Al-Hussein) said: "Come down from the minbar of my Grandfather". Omar said: "Wait a second, o son of my brother (Rasulullah)." Al-Hussein then grabbed Omar's garment and repeated what he said until Omar stopped his Khutbah (speech) and descended the minbar (pulpit) and finished his prayer. Once Omar finished his prayer he asked for Al-Hussein, once he (Al-Hussein) arrive he (Omar) asked him: "Who told you to do this?" Al-Hussein answered: Nobody ordered me to do so." Al-Hussein repeated that three times. [...] At this time Al-Hussein did not reach puperty (i.e. he was a child).
