The Hadith you've mentioned where is it and what is the source? The one I've mentioned is widely accepted by the vast majority of the Muslims apart from those who hold grudge against Ali. Love the Ansaar doesn't mean accept and take what ever they say and do.
Why did they gather in Saqifa and what was the point when the Messenger (s) had already dealt with the matter and left two WEIGHTY things behind for the Ummah to hold on to, to keep together and not to separate? Who were better than the Ahle Bayth and who was more better and worthy than Ali to govern?
The following verse;
"take what the messenger gives you and abstain from what he forbids you."
Did they (Ummah/Sahaba) take what the Prophet (s) gave them (the two weighty things)? Neither did they and nor have you.
The Hadith of the Ansar I gave you is also widely accepted and narrated in a ton of books. Here's a link to Bukhari:
http://muslimway.org/prophet-muhammad/369-Sahih-Bukhari/Merits-of-the-Helpers-in-Madinah-Ansaar/5157-the-prophet-said-qthe-sign-of-belief-is-to-love-the-ansar-and-the-sign-of-hypocrisy-is-to-hate-theWhat're you going to do now? Of course, due to your weakness of understanding, you created a conflict, you bashed two narrations against eachother.
I can say likewise:
"Loving `Ali doesn't mean to accept and take what ever he does."
Secondly, who told you the Prophet (saw) dealt with the issue with Thaqalayn? Do you understand what the word Thaqal means? Weighty and burdensome? A responsibility of those two elements was transferred to us but it was no appointment. If he (saw) told us to take care of his family, that doesn't mean he appointed them as leaders.
Why would you even quote Thaqalayn? Where does it mention `Ali?
The Prophet (saw) narrated in the authentic that he'd travel through any valley the Ansar travel through, have you followed the Ansar in Saqifah?
