Murder falls under intolerance. Religion can exist without being intolerant, but often doesn’t. The smell test really is pretty simple: if you’re not actively hurting someone besides yourself, you should be tolerated. Along with that, we decide that intolerance for other reasons (ie, because of a person’s genetic makeup or mode of expression) is itself harmful.

Now we can find tune and dicker about where that line of injury is, and of course there are special cases where the alleged hurt is spread around and it’s hard to decide how to adjudicate that, but that’s what the law and all its apparatus is for, after all.
