Firstly it would be nice if you could discuss without the arrogance and ignorance. Secondly do educate yourself before discussing and debating. Try to understand and get to know. Be familiar by finding out. If you don't know what Imamah is and you don't want to know but are raised to criticise and condemn it or to mock it then this is what you get, arrogance and ignorance.
Brother, what I found was in a booklet; I only have a few booklets that highlight the main traditions in Al-Kafi (mostly dealing with usul). If I were to find the entire volume, unabridged, like you find our texts online in many languages, I can present narration after narration that you would not know what to do with. One narration and not a single satisfactory response. I am waiting for brother whoaretheshia to invest some of his time in such narrations; he is failing miserably with our texts. Wallaahi, if you personally - from your own desires - declare this hadith to be weak or rejected, I will never use it in a discussion again.
The purpose of my exercise was to show you that we can play this game just as good as you, perhaps better than you. Shias come with extreme arrogance and ignorance, and often I see the same people recycle the same arguments (to use against Sunnis) even when they have been utterly refuted. So you must educate yourself with our standards first. I am requiring the same from you which you require from me.
Lastly, as you may know, I am a frequent member of three Shia mosques in our area. In one mosque, the imam - to my face - about 2 Muharrams ago, said that Imams (ra) are everything you imagine Allah (swt) to be but a "notch lower". He said that Imams (ra) possess all attributes of Allah (swt) but a "notch lower", or to a lower degree. And his mosque is the most moderate of the three I visit. He is my teacher; I respect him because he is honest about his beliefs. It bothers me, for example, when I see Shia debaters (like the clown in UK, Zain, at Speakers Corner) talk about "three positions" regarding belief in Imamah.
