Are you saying that anyone who does business with Moslems who've immigrated to the U.S., subjects himself to Sharia law?
Then things are just as bad as the "hysterics" say they are -- Moslem imnmigrants are purposively bringing their Prophet with them, and the choice of submit or die to everyone in America.
Care to rephrase that, if you got it a little bit wrong?
Asked and answered. See above.
