There are approx 10 million Muslim in America. Some say 7 million.
That’s more than 1%.
According to their data only 1% in America prefer to name Islam as their religion.
I would assume there are more than 3 million Muslims in America, but only 1% feel strong enough about their faith to consider themselves Muslim.
So if they are apostate Muslims I seriouly doubt they are about the strap on suicide belts.
