Hmm... I'm not sure we'd lose players over it. At least, I hope not... After all, there's a lot of different kind of people in the world.  Besides, wouldn't it be hot if some of the students went on to become teachers here?  Personally, I don't think it would hurt the game to have a few students be different from the norm.  It might even make it more interesting.  Having some diverse characters can be fun too.  Unless I'm missing something... I feel that this could work.
