The left says Islam is a religion and the gov't cannot interfere with Muslims. Just because the Holy Koran says that infidels must be raped, killed, harassed and even beheaded is no reason that ALL of them must be removed.
Just because the Holy Koran says your wife, your daughter, grand daughter, maybe even you can be made a sex slave for their pleasure is not justification to stop immigration. It is what is best for the world, so get out of the way.
