Sorry, dude, but I don't put any value in hate speech. And I don't care too much about the "Free speech trumps all" notion.
If you want to gas Jews you don't deserve a public podium. Period.
This "free speech" notion is exactly the reason why the right-wingers are on the rise once again - they're allowed to lie and give voice to atrocities. Nope. Not having it. As soon as as you openly and consciously spout forth hate speech and lies, you lose your right to an open podium.
