During a recent interview, the creators of South Park had this response to Reason Magazine:
Stone: I had Birkenstocks in high school. I was that guy. And I was sure that those people on the other side of the political spectrum were trying to control my life. And then I went to Boulder [Colorado] and got rid of my Birkenstocks immediately, because everyone else had them and I realized that these people over here want to control my life too. I guess that defines my political philosophy. If anybody’s telling me what I should do, then you’ve got to really convince me that it’s worth doing.
I think they may have a point.
