First off, freedom of religion per the constitution meant freedom of various Christian Sects and not any and all religions of the earth.  Liberal progressives would not agree with 100% of what I say and also what the American majority sez.  So...They invent Politically Correct speech to try to dissuade, prevent, muzzle any and all free speech THEY do not agree with.  This threatens our nation to the very core as it is designed to operated on a certain Western civilization frequency like traditional folkways, mores, values and law and order.  Take that frequency away ( and the left at the top of the food chain know this. like Soros) and the system will slowly crumble like it is doing.
