As long as media and politicians are saying "Islam is the religion of peace" and burying the underlying problems, no progress seems to be made. It may indeed be that the majority of Muslims are peaceful, but it is also undeniable that:
(1) polls show a sizable minority support jihad and even suicide bombing
(2) results world wide show wherever there are Muslims some of them commit terrorist acts,
(3) world wide wherever Muslims gain large numbers, they act politically and violently in ways that harm other peoples rights.
It is sometimes said, in defense to discussion of passages in the Koran that call for violence and evil, that there are bad passages in the Bible. But Christianity has gone through a reformation. Islam hasn't. Perhaps a ban on Muslim immigration will spark a reformation in Islam.
