In this blog's brief life, the most frequented post by far addressed the question of whether black men prefer white women. My tentative conclusion was that they like light-skinned blacks with European-ish features, but I haven't run across the data to test the idea.
Standing in line at the supermarket last night, I opened the latest issue of Ebony which featured an article on "Who is Dating Who?" [sic]. The magazine also featured other famous couples. I counted 19 couples, and the darkest, most African looking women by a wide margin was Mrs. Barack Obama shown in the top photo. (Evidently, Barry wanted to prove he was black enough when he chose Michelle). She really was an outlier.
Much more common were women like Porschla Coleman who is dating Russell Simmons (shown in the bottom photo). So, my second (unscientific) stab at the same question produces the same results.
This pattern is consistent with my tastes, by the way, only in the reverse direction. Lighter white women can be beautiful, indeed, but beautiful like a painting. It's the darker white women who really stir the blood, as if a little dose of the exotic is necessary. There were few black men with pasty girlfriends. Too much exotic can turn someone off.
