"Free" is not a characteristic of the content of the speech; it's a characteristic of the consequences of such speech.
You're right that this speech wasn't free, but that's because the kid's in jail, not because it's "nonsense".
What is more wrong with society, in my opinion, is that we interpret "the right to free speech" as "the right to say nonsense".
When you say that some speech doesn't deserve freedom because it's "nonsense", you give those who want to silence speech an easy way - just label it as "nonsense". And after all, ideological dissent is almost by definition "nonsense" to those who believe in the status quo.
By "nonsense", I mean inflammatory speech with no defined purpose. I base this on social norms because this is a society.
I get the argument you're trying to make. 99% of the time, I'd roll with you. The real exercise of free speech in this whole thing is our dialogue, which I will fight for. I'm not going to fight for Cammy Dee, however.
You can call his words whatever you want. I'm not signing a petition or going to war to protect Cammy Dee. This is not free speech.
I'll save my energy for Ai Weiwei,
EDIT: Thanx!
