And so should judaism, which, shock horror, also carries out practices like circumcision and terrorizing of secular jews.

Not to mention right wing christians who bomb abortion/reproduction clinics and synagogues.

There are extremists who only look at the medieval parts of their "book", in every religion imho.

I think circumcision of young boy-childs came about to save them from infection and death caused by sand irritation- but in any event it doesn't seem to do them much harm.

You are right, we do have enough Christian nutters of our own, so why bus in other types of nutters, as if we don't have enough of our own. In any event we can't ban everybody but we can ban Muslims who persecute women and gays.
