Okay, so he replied again and I just want help formulating a final response:
Since that Rafidi has lost the argument, he is making silly arguments for damage control.
A Khariji could use same stupid logic as this Rafidi and blame the responsibility on Hasan(RA) for killing of Hussain(RA), He could say that because Hassan(RA) gave Caliphate to Mu'awiyah(RA) , he(ra) was able to make Yazeed as Caliph and all of this occurred.
So you see, there is no end to the stupidity of people, they can run the horses of their stupidity to any extent.
Infact Mu’awiya(RA) is absolutely free from the stupid allegation he made, if we read the report mentioned in Shia and Sunni books.
Hadrat Mu’âwiya’s last advice to his son Yazîd as he was dying, as follows:
و امـّا الحسين فـقـد عـرفـت حظّه مـن رسول الله و هو مـن لحم رسول اللّه و دمـه و قـد عـلمـت لا مـحالة انّ اءهل العراق سيخرجونه اليهم ثمّ يخذلونه و يضيّعـونه ، فـان ظفـرت به فـاعـرف حقـّه و مـنزلة مـن رسول اللّه و لا تـواءخـذه بفـعـله ، و مـع ذلك فـانّ لنا به خلطة و رحما و ايّاك ان تناله بسوء او يرى منك مكروها.

“You know what relation Imâm Husayn ‘radiy-Allâhu ’anh’ is to the Messenger of Allah. He is a part from the beloved Prophet’s blessed body. He is an offspring from the flesh and blood of that most honourable person. I understand that the inhabitants of Iraq invite him to go there and be with them. But they will not help him; they will leave him alone. If he should fall into your hands, behave in appreciation of his value! Remember the closeness and affection of the Messenger of Allah ‘sall-Allâhu ’alaihi wa sallam’ to him! Do not get back at him for his behaviour! Mind you don’t break the substantial ties I have established between him and us! Be extra careful lest you should hurt or offend him!”
