Mages are intelligent characters as well, so there's no way you could identify yourself with one...
Forget your bigot complains and just enjoy the game.
Why do you feel the need to insult my intelligence for requesting that I be able to play as a white mage? That's sort of a wierd jump to make. Is it your opinion that nobody should be able to play as a white mage or is it something different? You'll notice here that I'm not hurling insults at you, just trying to understand your point of view. I want to play the game as a straight white male magic user. There I said it. What a crazy world we live in when something as innocent and harmless as that is labeled as bigotry. Where's the bigotry?
Please forgive me. I seem to have some strong prejudice against racist people and my post was rude.
Let me rewrite it in a non offensive manner:
Mages have amazing magical powers and spellcasting abilities, things that you don't have IRL, so it's difficult to identify yourself with one...
Having that in mind, don't pay attention to other menial differences (like eumelanin levels of the character) and just enjoy the game.
