I don’t honestly see the connect between what Muslims want in America vs. what is happening in their home countries. Presumably Muslims that come to America come for its opportunities and freedom and to escape the oppression, lack of freedom and economic corruption of their homelands. They may be of quite different mindset than those who remain in the Muslim countries.
Islam, unlike the Catholic Church, does not have a single authority, nor is it a single monolithic form. There are Shi’ites, Sunnis, Wahabbis, etc. They don’t always get along between themselves, and show considerable prejudice between each other, much as Catholics and Protestants do in some parts of the world.
I work with Muslims every day, and I have no quarrels with them.
What I do object to though, is that in my country (Canada) at least, we do bend over backwards to allow freedom of religious expression to immigrant groups (not only Muslims) but basically treat Christianity like a disease to be wiped off the face of the earth. I suspect the same mentality also exists in the US to a certain extent. If we have religious freedom, it should apply to all, including our own traditional forms of Christianity.
