Well, we've gone off the rails here, now haven't we? I'm more with Xenon here. Citizens have a right to be Nazis, a right to be white supremacists, a right to think the white man is the greatest evil ever. Whoever it is you hate, you can do so without fear of the government. or you should be able to.
Hopefully our collective moral sense will keep these cretins from going too far. It's what they do, not what they say. Suppressing them means we can suppress whatever is not currently fashionable.
