Should Religious Liberty apply to all religions

Recently, there has been lots of controversy over how we should deal with members of certain religions, and whether or not generalizations should be made based off the actions of a few individuals. Politicians like Ted Cruz are quick to endorse religious liberty for all Americans, and even push for America to be based off of Christian or Jewish values. He also wants stricter surveillance and possible restrictions on Muslims. My question for you, users of offtopic, is this: should all groups be protected equally by the constitution, specifically the 1st amendment, and if not, should every amendment and other components of our legal system only defend certain groups? Example: A pagan man kills 30 people with a gun, and he claims it's for his religion. Pagans make up a small percentage of Americans, so it's safe to assume that pagans are violent by nature. Should pagans have their right to bear arms taken away, and even have their religious liberty infringed upon? The purpose of the post is to spark genuine conversation in a civil manner.[spoiler]haha right[/spoiler] So can we be respectful and open to new ideas?
