Pathetic.
Homophobia at large in the US once again, and emotional damage? Get used to it dear, you'll be seeing a lot more. I'm actually so utterly offended at them suing for damages, I suddenly feel like the family have emotionally damaged me in the process! That'll be $4,000,000 please.
Besides, there is a clause on the age rating for educational establishments if there's a good reason. My tutor told me about it at college (I'm 22, but some students are under 18) and we watch a tremendous amount of 18 rated films as part of our course.
