Why do you assume that the women prefer one race over the other?
Have you really never met any women who say things like "I only date black/white, etc men"? It's not only white men who tend to prefer their own race, believe it or not! ;)
Maybe they just don't care about the race of the person they're with?
Or maybe they do?
Just because you prefer
one race, doesn't mean you hate
the rest. Even those who like to "mix and match" a bit often go back to their own kind eventually.
I used to know a girl who spent a very long time ONLY going out with black Africans - but when she decided to have children, she found herself a white man instead. I must admit I was very surprised! I'm sure that some of us have a few theories about why that may be, but I'm not in the mood.
