No.
Yeah, right, your just defending his freedom of speech?
So what else do you defend; pedophiles? Nazis? Terrorists?
The Founding Fathers never intended for freedom of speech to include speech that is inciteful of violence or panic or is generally harmful to the public good. That is why a good majority of them supported the Sedition Act.
Why dont you just admit that you hate this nation and want to protect anyone who undermines it?
Or are you just too naive to realize that people like Churchill are only 'good' when they are room temperature?
