I'll quote a movie. Not the same context, but the same principle:
[FONT="]America isn't easy. America is advanced citizenship. You've gotta want it bad, 'cause it's gonna put up a fight. It's gonna say, "You want free speech? Let's see you acknowledge a man whose words make your blood boil, who's standing center stage and advocating at the top of his lungs that which you would spend a lifetime opposing at the top of yours." You want to claim this land as the land of the free? Then the symbol of your country cannot just be a flag. The symbol also has to be one of its citizens exercising his right to burn that flag in protest. Now show me that, defend that, celebrate that in your classrooms.[/FONT]
Then you can stand up and sing about the land of the free.
