I've been watching this thread and fighting the urge to comment but I have to say I have looked at the link twice and the second time it strikes me as more disgusting than it did the first. I don't think it's that acceptable to imply that we should just ignore the racist bits, and even if you do, the rest of the 'jokes' are still bullying and hurtful. I would be mortified if that happened to me.
Also, AIBU is quite volatile at the best of times. If you ask AIBU then you must be prepared to be told you are. I think YABU to link to this site and ask if it is a good example of trolling. I'm glad there are people here who are letting it be known that they think it is unreasonable too.
It makes me feel a bit sad that someone has actually sent these to real people then it has become passed round the Internet and bragged about. I agree with posters who have thought about what they would feel if their child was doing this to another person, or had it done to them. I would want people to have better values.
I do understand that some people wouldn't be offended if they got sent a picture like that and would just find it funny. I think they're very lucky to have such robust self-esteem, however a lot of people really struggle with their looks and feelings of unattractiveness and I think in an ideal world we should not make comments/laugh about someone's physical appearance, no matter how innocent the intention.
As others have said it may be a natural immediate response to find some of the images funny, but as in other situations, we should think about the effects of our actions and if we really want to respond in that way, and modify our behaviour accordingly. In the same way I might feel instantaneously really envious of a friend's good fortune but then I would think it over, realise it's not fair and then be happy for her.
I don't know if I sound really boring. I like to think of myself as quite a fun person, just not at someone else's expense if I can help it.
