One also must consider the person's surroundings in their choice of dating partners. If one is surrounded by a majority of people of another color, naturally there is a greater probability that they will end up dating someone of another color.

For instance, I went to a small college in New England. At that school, there weren't many women of color. Those that were there were pretty tightly knit chiefly around their race and gender. The hilarity that ensued when the men of color dated a woman of color on campus, broke up with them, and then tried to date another woman of color on campus could be the basis of a reality show. A 'Fear Factor' centered around mating rituals, if you will. The catch is, if you crossed the color line to date, you'd be ostracized within your own group. You were doomed either way. I pitied the poor soul that tried to toe that crazy line.

Of course, one could have went to another campus for their loving, but the idea that I'm trying to illustrate is how different ways of thinking and relating to one another and their choice of lover can cause unfortunate friction. I'm sure that some people are numbskulls that believe that by dating another color that they have "made it" or are "dating up", but just as many aren't and are just behaving as would be expected within their environment.

Hope it made sense. :)
