ptah:
1) Because, as a white boy, you are naturally attracted to white girls, and all white girls like black men.
2) Because attractive white girls are not interested in creepy white boys, and prefer big black men. So giving them money is one of the few methods of gaining their acceptance.
3) Because they, and their big black boyfriends, are better than you, and you know your place.
4) See above- it is the only way a creepy white boy can get close to a beautiful white woman.
5) Everywhere.
Thank you for your insight Ptah !
