I looked at the top 500 'hot' people on POF... it looks frighteningly Aryan. I mean, vast majority was blond and blue eyed. Only 1 black woman out of 500. Two asians. No 'indigenious' looking Latinas.
'Frighteningly Aryan? Is this because POF is a world-wide dating site, primarily including people from Britain, Scandinavia and the rest of Europe, Australia, Canada, New Zealand and the United States? I don't know the percentage of other racial groups on POF, but maybe it's low? Maybe it's a website-participation issue, rather than the latent-racism issue you're suggesting?
We all have our preferences with who we date, and these are based upon numerous factors, not only race. If I were in America I'd be happy to date an African-American woman, the same as I'd be happy to date a woman who was in my age-group with a similar lifestyle to me. Attraction is not race-specific, but cultural, social and religious issues often come into play if we are talking about a relationship.
For the longest time in Western history, white has symbolized virtue/purity/beauty... and black evil/degraded/sexualized.
Maybe America now has the opportunity to dispel this conception with it's new president? The first family is classy, poised, powerful and quite black. Michelle Obama is an amazingly beautiful woman without a blonde highlight in sight!
