Now, I'm not saying you should listen to Weissberg very often. He's obviously a completely wrong about just about everything. But that doesn't mean he's wrong about political correctness being a bad thing at times.

Are you being offensive if you call Weissberg a racist? I think it's a horrible thing to say about someone, but you should still have the right to say it. It's not a base insult, it's an assertion of a fact, and facts can and should be debated.
