During WWII we didn't let Germans into our country. Why? We were at war with them. We wouldn't allow Japanese into our country. Why? We were at war with them. We even rounded up Japanese and other asian decent people born and raised in America to ensure they weren't a threat. I don't agree with that last part. But, why are we so worried about offending a group of people when we can't tell the good from the bad muslim any more than we could tell a good German from a bad Nazi? There are plenty of other countries they can immigrate to that they aren't blowing up and committing terrorist acts against. Keep them out of the countries that their extremist brethren are blowing up. To me that's not discrimination. It's common sense.
