I think there's a definite social attachment to sexual attraction, and not just the very basic 'I dig their personality' thing. For instance I'm sexually attracted Arabs. Not only are they generally more attractive men, but I'm part Hebrew, and there's something really sexy about the fantasy of fucking a terrorist. In addition it's a race that is predominantly religious and there's a certain passionate fucked up righteousness that, while obviously retarded to me and my superior scientific mind, is nonetheless titillating when compared to the cold nihilism of most other men.
I think an attraction to white women could be due to similar factors. They've been historically in the home as wives and mothers, subservient to their master husbands, and even today most of them have it ingrained that someone needs to take care of them. Black women historically have had to work equal parts in the home due to racism and lower wages for their husbands in the workplace, so there's not as much penis worship going on. Asian women tend to be go-getters who run. That. Shit, which is equally terrifying to a man with low self esteem who wants to be the celebrated provider. Indian women are comparable to Asian women, Hispanic women are comparable to black women, and Arab women are comparable to white women, with the added distinction of wanting to be free of patriarchy but still being trapped by a dominant religion. White women trap themselves.
In other words I bet you're equally attracted to Arab bitches because they'll suck your dick and say thank you. Noice.
