i try to be, but to be honest i don't know why. the only people who enforce them are self righteous saints who still tell you not to smoke but don't realise it's only because they were told not to by someone else, or R.E. teachers, or history teachers, or any teachers to be honest. most people are completely fine with it, but i draw the line at racist names like "paki" and "chinky". I'm okay with black and white though, as Jedoro said, it just saves space, i would feel a bit odd being called "caucasian", when i'm clearly white as vanilla.
