Belief without action is dead.
If you are not trying to advance Islam by all means at your disposal (i.e. Jihad), you aren’t a very good Muslim. Islam is pretty specific. Believers are to fight the infidel until they convert, are subdued and pay the jizyah, or, until they are dead.
I agree, but you missed my point, which is that we can make a million laws against "beliefs" but they would be unconstitutional and unenforceable because we can't just read people's minds and decide they have criminal "beliefs".
That's the problem with so-called "hate crime" laws too. People's "beliefs" alone can't hurt anyone, if they take no action. We must keep, and enforce, laws against criminal behavior. And not just after an attack. We must enforce laws against terrorist conspiracies also.
And never let anyone off the hook just because their criminal behavior was supposedly required by their beliefs.
