Censorship is the answer. I used to get kicked out out of class on a regular basis for wearing "safe sex" shirts. Lol. I used to ask my mom "do you want to come get me later for lunch and hangout?" If she said yes I'd go to school in one of my shirts:
Big Dicks Condoms
Nibble My Nuts
All some of my favorites all got me asked to leave lol. It became a contest between me and the school and as long as my grades stayed high my parents didn't care.
Free Speach dude!!!!!!!!!! It is worth the fight!!!!!! I'd sew an Obama and Romney shirt together and wear that ****er to school next!!!
