Freedom of speech is freedom to say what I agree with

Here's an infuriatingly daft quote from not the unlikeliest of sources, Sean Penn:

(...) Every day, this elected leader [Hugo Chavez--p.], is called a dictator here, and we just accept it! And accept it. And this is mainstream media, who should--truly, there should be a bar by which one goes to prison for these kinds of lies.

Isn't it interesting that those who demand that the government have the power to imprison people for saying what it considers to be lies, always assume that said government will be in perfect agreement with them as to what is and what is not true?

Either that or what they're really saying is: "I wish I had the power to put people in prison for saying things I think are lies."
