Ergh, you people.
This thing got a chuckle out of me, I have to say. The World Trade Center bit didn't make me laugh, but I'm not going to go on some self-important tirade about the importance of freedom and making sure that NOBODY EVER makes fun of that, because it's stupid. People have different senses of humor, and if it offends you or doesn't make you laugh, tough shit. It's making somebody else out there laugh. It's the same thing as racist jokes, I daresay. So get off your high horse about all the people "that died for his freedom to make this," because you didn't exactly die for his freedom to make this, now did you? Sometimes the best way to heal from something is humor. At least let the man try.
