> your faith is also a political institution

This is half-right. Islam does have its own political system, but the faith is largely divorced from that system.

I'm fairly active in my mosque and ive met a lot of community members running for various levels of public office. None of them are calling for Islamic jurisprudence, and none of the policies they promote are obviously "anti-American," unless you consider a higher standard of living for the lower and middle class or higher accountability for the ruling class anti-American. I suppose historically speaking those concepts are anti-American but whether that's a good or bad thing can be left as an exercise to the reader.
