Leaving the political aspects of banning a particular religion aside, I think that the Patriot Act and uniform shall-issue CCW laws in all fifty states or, better yet, Vermont style gun laws in all states can go a long way toward putting the damper on terrorist activities by domestic muslims.
I believe strongly that everyone deserves the right to practice their religion regardless of how wierd others may think it is as long as otherwise no laws are broken in the process. The fact is, there are millions upon millions of peaceful followers of Islam. They have a right to follow thier religion. Another established fact is that the Islamic faith spawns terrorists, ergo: Moslems need to be watched, we must be prepared to defend ourselves and they must know that we are watching and are prepared and have the will to act if they show the slightest sign of acting up.
Banning one of the worlds major religions would strike at the very heart and essence of the principles the United States of America was founded upon. It cannot be allowed.
