With our permanent Government's (NSA, CIA, ect.) ideology and the mood of U.S. civilians; I don't think there is any reason to worry about "sharia" law being adopted as a religious freedom. Is there any indication of this other than some Muslims' complaining?
Saoirse-
I don't see how AIG's promotion of a fund that doesn't pay interest nor benefit from gambling, entertainment, alcohol or pork and Muslin immigration will lead to the US adopting "sharia" law.
If it makes you feel better about those damn NY'ers: Unlike your friends here I wouldn't move if you started building a wall around me; I would shoot you.
Added: I did not know Saoirse was female when I wrote this. It was before her avatar and there was nothing to indicate gender in her profile at the time - but that is no excuse for lack of thorough research on my part.
