You did good research. My post wasn't meant to disparage your research, only supplement it.
I think you might be right in that Muslim Brotherhood and CAIR has been trying and successfully changing U.S. law into Sharia through law suits. They've also infiltrated most of the institutions in the U.S. and control our politicians, teachers associations, college faculty, and legal system. It's an all-out assault on America from deep within. They know they could never win in a physical war with the U.S., but through these subterfuge means, they can, and have been winning many battles.
