They don't belong here in ANY case.
I don't have any problem with immigrants of any stripe, as long as immerse themselves in the spirit and customs of their adopted land, and of course immigrate legally.
The problem is, most Muslims, most immigrants in general these day, do not want to do that. They want to come to America or Europe and demand that the people there accommodate them and adapt to their culture and beliefs.
Hell no. If you make the decision to leave your country behind and come to a new land, as a consequence it is incombent upon you to live within the norms and beliefs of your adopted land. Don't work to make the new land just like your old land. Why did you leave in the first place?
