Although I'd like us to be a Christian nation -- I know that is never going to be the case - until Christ comes back again. So non-criminal Buddhists, atheists, pagans, Hindus, etc, should be allowed in through the legal immigration channels. But Islam IS different. Their 'holy' book tells their cult to either convert, enslave, or kill those who won't join their cult. That is a fundamental difference from all of the other so-called 'religions'. Yes, there are whack-jobs amongst all people -- but when you have a group that swear allegiance to a book that tells them to destroy those that don't join, you have to have a death wish to invite them onto your shores.
I understand that many of us know Muslims that are up-standing and wonderful people. It is God's mercy that a large percentage of Muslims don't pay attention to their book - but unfortunately a lot of them do, and you never knows if the ones that don't (the ones that are wonderful today) are ticking time-bombs waiting to be 'infected' with that old-time religious fervor. Great when this happens to a person who becomes a Christian as they are changed for the better, deadly when it happens to a person who becomes a believing Muslim.
BTW, Your screen name is one of the greatest movies made.
