I don't know what it is if it is not history. When you stand corrected, you try to give it a damn. Wow, what an approach. The point with self proclaimed atheists is that they first try to sit on a high horse of morality built upon some flaky logic and when they are brought down from that high horse, they tend to give a damn.
I did not make your point at all. I presented a detail of Muslim History. There was no Shia-Sunni massacres after Imam Hussein's death. There was no civil war infact. So here you go, you stand corrected again. Moreover so that you understand better, Imam Hussein was not shiite nor was his progeny.
