Why should I support political correctness?

I agree with you on the last three paragraphs. Children are not legal adults so they shouldn't be allowed to expose their bodies. Even still, why would you wanna look at a naked twelve year old boy/girl? Also, drugs make people a bigger burden on the government and the tax payers. As long as it doesn't affect other people in any way (besides just offending them morally, and a few exceptions I'm sure people can and will think of) I feel it should be legal.
