Um, no, they wouldn't. They're as American in their outlook as you or I. I have a feeling that you don't really know any American Muslims well.
This is how they run their own countries and how they want this country to operate.
The Muslims I know, at least, moved here (or their parents moved here) because they were sick of the way things are run in their native countries. They like living in the US where they are free to live their lives peacefully and freely without interference from radical mullahs.
ask if they think Sharia law is good for a community and if you'd be better off if you'd only revert to Islam.
None of them have shown the slightest interest in converting me or in sharia law. Like I said, they moved to this country for freedom and opportunity, not to recreate the countries they left.
they don't really believe this, but they have to go along with the tenants of the religion so they are not punished by the Imans.
Two of the Muslims I know are lawyers (including a Federal prosecutor) and one is a defense contractor. They have no fear of some radical Imam (not Iman- that's a model married to David Bowie) telling them what to do. And the word is "tenets," not "tenants."
