And that "paradox" boils down to the intolerant saw of "you're not tolerant if you're not tolerant of intolerance"
It's a paradox b/c it's not really a paradox, but it seems like one, when couched disingenuously.
But it's like freedom. Can you really believe in freedom if you believe in law and punishment?* But can you truly be free with criminals running amok? So to have freedom, you must restrict freedom of those who would take away your freedom.
