What those people need to do is stop trying to claim some kind of special status based on sexual orientation. Most intelligent and rational individuals don't care about such things that have no effect on them personally. However, when people have a very in-your-face attitude about needing to be special because they are "different", it's annoying whatever the reason for it is. Bragging about it to people who could not care less invites harassment on themselves. Too busy flamboyantly shoving it in people's faces to even realize, and then they blame others for becoming tired of it and expressing their opinion.
Not to mention this game and forum take place on the internet, where someone's gender is largely irrelevent let alone what gender they like to get freaky with.
