oh no, respecting people's identities. what the hell else will happen in this world?!?
your name is "pcgeek". but what if i called you "compuwiz" instead? you'd say "no, my name is pcgeek" and i'd say "but you look more like a compuwiz to me, so i'm gonna roll with that even if it pisses you off". and that would make me an asshole for not calling you by YOUR name for YOURSELF.
likewise, do you call a married woman who has taken her husband's surname as "Mrs. {maiden name}" or "Mrs. {married name}"?
it's the same goddamn thing. don't be an asshole.
