We are not hear to discuss trans gender. That is a different debate entirely. But if you want to.
Trans has more to do with the biological makeup in terms of your brain. This simply has to do with the fact that you didn't get what you wanted at birth, regardless of the fact that nothing is wrong with the way you were born. Your race was not a mistake biologically. Your race has to do with your parents (Unless you are albino, but that's a very rare case). There is no real reason to want to change your gender unless you're too bitchy to deal with racism.
