Is South Park and their creators hypocritical about premarital and abortion?

Well, I'm pro-choice, but I don't know that I'd call that hypocritical. I don't believe that premarital per se leads to more unwanted pregnancies. I'd say that at too young an age leads to more unwanted pregnancies, and at a young age is more likely to be premarital. Nonmarital by mature people doesn't do that, I don't believe. So it's not true that premarital automatically leads to unwanted pregnancies.
