Why does Caucasian mean white?

Caucasian comes from the word Caucasus which is a region encompassing the countries of Armenia, Georgia, Azerbaijan, and parts of Russia and Turkey. Most of the people in that area aren't "white".

Homosexual is some sort of politically correct bullshit. I was born gay, was gay all these years, and now all of a sudden I'm "Homosexual". Well listen to me, politically correct rednecks with a unraped, tiny asshole the size of a peanut: I have not been born Homosexual, so I'm not fucking Homosexual! Get that into your heads, you morons! I'm fucking gay, G*A*Y! And fuck you all, damn you slack-jawed inbred trailer-trash.
