HAHAHA, Blizzard actually bent the knee to that?  What I don't understand about this type of behavior is why capitulate to people that will never play your game.  Seriously though, in TF2 the only character that had a sexuality was the Spy and the only reason for that was because it was part of story in the Meet The Spy video.  Hell, as far as I know the pyro still doesn't have a gender.  Wanting to give sexual preferences to digital characters when it doesn't further the story of the game makes absolutely no sense to me.
