"You've never laughed at someone with a mullet, a fightin' attitude and an intolerance towards gays and NASCAR-haters? What DO you laugh at?"
You're just being obtuse. Do you really think most people with a mullet care what these guys think? They can sit and think what they want, I don't give a damn. There are southern comedians that make jokes about that kind of thing all the time. No one stones them. The guys with the mullets even laugh.
When you show up with a camera crew and three cars, painted garishly with insults and things purposely intended to make people angry, it isn't about their opinions any more. There's a difference between stating your opinion and taking a circus to a small town to PURPOSELY antagonize people. Worse, when your video is INTENDED to demean the people standing there, heavily edited to make it as bad as possible?
The difference is Phelps making a website or a TV show saying god hates gay people, and Phelps showing up at the Fantasy Fest in San Fransisco waving the signs in people's faces. Most of the mob wouldn't normally get up out of a chair in response, yet when they are there, in your face, antagonizing you, it would be a pink, fuzzy abattoir.
They obviously went there to bait people into anger, and they got so little they had to edit the video heavily to show it. It's sad. What is saddest is that the REAL act of intolerance was the one you are calling funny.
