Nice thought but, then where do we stop... Do we kick out the Radical Christians who terrorize and have the potential to bomb clinics because they perform abortions.
Do we kick out the KKK because the terrorize Blacks, Gays, Jews, etc..
Where do we stop?
I agree this is a big problem what do we do when there is a group of people who may pose a threat.
Remember what we did to the Japanese, and just in the new this week high school degrees are finally being given to those Japanese who were put into concentration camps in America just because they were Japanese and they might attack us.
It is a very hard thing to do when we choose a group to isolate because they could cause harm. But where do we stop, and what about those who will be falsely accused and have to be kicked out because they are Muslim.
Remember guilty until proven innocent.
I know you are not talking about kicking out all Muslims or those of Middle Eastern decent but it could lead to that as our too far right radicals in America start beginning to discriminate against those related to those who are kicking out.
