I’m sorry but all sorts of “odious” philosophies are protected by the first amendment included socialism, Nazism, Communism, and Obamaism. The first amendment does not make distinctions. If you don’t like that, either move to Russia or propose a constitutional amendment.
What isn't protected by the 1st is any call to murder or enslave people who don't believe in your religion. Period. The Courts have held that time and time again.
You're wrong.
