... sometimes people that post in AIBU are incredibly defensive if they are told they are, in fact, BU?
I know sometimes it isn't easy to accept (having found myself in that situation before), but if the majority of people think you ABU, surely then it is time to stop and think instead of getting angry at the people that have answered your post (after all, you asked the question in the first place, so you must have thought you might be!) and defending your stance ferociously and sometimes digging youself and even deeper hole?
I have seen this quite a few times now, AIBU to just smile (sometimes laugh) and move on to the next post?
