The dark men dating light skin shouldn't really be a talking point. (for most dark skinned men)
Let's just look at this from a logical perspective. The darker you are, the more the odds are you will date a lighter person. The lighter you are, the more the odds favor you dating a darker person. If you put the black race on a shade scale, what percentage of black women would be darker than the darkest black man for him to date? The answer is 0, so he would have to date a lighter woman. So the "best" he could do is match his hue, which would be 1% of the population. The other 99% of women would be lighter in complexion.
