things that i think most people would find offensive:
- eating disorders
- depression
- race
- religion
- child abuse & sexual abuse
- rape
- the genocide of the jews in world war 2 (certain people might find it funny)
it depends on who's telling the joke & who they're telling the joke to of course. what is hilarious to 1 person may be very offensive to someone else & what is offensive to 1 person may be hilarious to someone else. political correctness is subjective but there are some lines that shouldn't be crossed. borat was a movie that definitely crossed the line many times but people still found it funny.
like most people i don't like being the butt of the joke. i find it hard to laugh at things that i have done that were humiliating. some people would be able to laugh it off but not me. i just take things too seriously. i do have a good sense of humour though. i'm interested to know other people's views on this.
