There are parts of the constitution that protect people we don't like. The difference between people like me and leftists is that I will stand up for the rights of people I disagree with even people I don't like.
“there are several constitutional amendments protecting them”
There are a few things you need to think about. Firstly, constitutional protections of religion are not limitless. It was decided that Mormons did not have a constitutional right to polygamy.
There is no constitutional protection for religions that might practice human sacrifice or ritual rape.
There is certainly no constitutional protection for a murderous blood cult that has demonstrated itself incapable of coexisting with civilization, a cult that practices rape and other forms of slavery, and which does not recognize our right not to be killed by them.
Expelling muslims is simple self-protection. If we fail to do so, our children will curse us for it.
