I would say that's pretty accurate. The spectrum of acceptable black "social personalities" seems to be smaller than for whites, at least in the high school years.
It is in part do to the fact that whites comprise a much larger portion of the population (70+%) in most areas, but also they don't necessarily (need to) express themselves as "white" as their defining social trait, so they may choose something else as the major one.
