Don't mischaracterize what I wrote. I didn't call for a ban on islam. I object to the exaggerated deference our leaders and the media give it.
People have the right to associational freedom under the First Amendment, yet that didn't stop the FBI from a large-scale effort to infiltrate the KKK. It would be an obvious first step to do the same thing with mosques, yet we are told they can't even be listened in on for fear of upsetting muslims. If the objective if such surveillance was to punish muslims for their religious beliefs, that might make sense. It makes no sense when we are talking about uncovering terrorist plots.
Dealing with radicalized American citizens is tricky. Non-citizens however do not have the same rights and should be deported immediately for jihadist rhetoric. That's a problem for this administration however, since they refuse to even recognize the existence of jihad.
We know for a fact that some percentage of muslim immigrants are terrorists or will become terrorists. It is not a trivial concern. We know from the experience of Belgium and France, among others, that when the number of muslims in a country increases, the task of tracking them increases exponentially, as does the risk. Our FBI has proven itself incapable of handling the number of muslims we have already. Don't forget, they had the 9/11 terrorists in their sights, the Boston bombers were well-known to them, as was the Orlando shooter. They should have picked up the San Bernadino shooter's wife's radical connections and refused her entry. Yet all slipped through their fingers. DHS' response is to further restrict our rights rather than address the actual problem.
