The only Muslims I know who are able to live peaceably in America are the ones who aren't particularly religious. I guess Islam is fine as long as you don't practice it.
My son-in-law is a Muslim (from Pakistan, naturalized American citizen). He is not religious at all as nearly as I can tell. From what I know about, and through, him and his family members and friends, I agree with your statement. Islam, when taken seriously by its adherents, is a serious danger to the West.
