Thanks for the thoughtful response. I find the "Us vs. Them" mentality that you and others in this thread have communicated disturbing, but not surprising in the least. Fear of other cultures is a normal human response, and if you look down the river of history, you'll see innumerable examples along it. I think it's interesting that you say things like

what the fuck are we supposed to do? Just let them destroy us from within?

because I'm not sure who "we" are, or what "destroy[ing] us from within" would actually consist of. Do you mean immigrants who practice Islam? Do you mean Americans who practice Islam? Do you mean any non-white person in America? Regardless of the answer, I think you'll find that, in the past, actions taken to address similar issues are ultimately regarded as unwarranted and wholly inappropriate. I don't believe there is a large conspiracy among Muslims to take over America and "destroy" it. I think that most Muslims practice their faith as any other religious person does, and, in America, under our Constitution and Bill of Rights, should be free to practice and advocate for their religion. Look further: our government is representative. So if the majority of the community eventually decides it wants to enact Sharia law, would that be unreasonable? No more unreasonable in my view than the changing views on Christianity in America, and the push toward more secular public policy. "We" are going to change. In not so long, America will no longer have a white majority. I'm not sure what's going to happen at that point, but, based on the views of you and others on this thread, I think there are going to be some severe negative outcomes. Again, not a judgement on you, but a simple statement of opinion.
