Reading this post reminds me of conservative Dinesh D'Souza's puzzlement over the complexity of the black/white issue. He makes many of the same points you do.

I do remember from college, however, that the one factor that is hardest to bridge in the entire world is skin color. Every Euro-based society has, at one time, placed blacks at the lowest end of the totem pole (see: Portugal, macaque). Surprisingly, this factor plays larger in most societies than culture.

John McWhorter (Losing the Race) is the only black writer I've seen who goes into detail to find the roots of victimology then disaparages this pointless excuse for failure. You'll not see public praises of his work from the black separatists, however, partly because he says too many things they don't want to hear.
