^yes, I agree people get wayy too offended these days, especially with some jokes.
on the other hand I think it's a bit rude to use the word cunt with someone you don't know, and to insult your teachers.. lesbians or not. there are better ways of putting them in their place. insulting them just gives them another reason to dislike you or think you're an idiot.
recently I went to see an anti-environmentalism (sort of) documentary at a film festival, and there were a bunch of pissed-off hippies there rambling on at the Q & A session afterwards. that doesn't really relate to the topic but it was kind of funny.
