To expand on my comment a bit more, I respect peoples right to do whatever they want to do, I don't feel gaming should be demanded to cater to every single person however, some people on this forum seem like they'd love to ban the use of gender words entirely which just seems ridiculous.
I'm a man, some people are women, others have a more complex situation and i'm sure most of them understand when a game designed for kids doesn't bring out complex sexual issues. I see no harm in making it more generic (character select screen, etc) but I sure as hell hope the usage of words boy and girl isn't outdated, that's ridiculous and almost all of society would agree.
Hell my security paper work ask your gender, I suppose I should contact HR immediately.
