Alternatively -- people aren't rational ideologues with clear beliefs and a coherent understanding of how and why we act: it might well be that for every person who is determined to uphold so biological hierarchy based on melanin pigmentations (or whatever), there may in fact be many more who are simply a little scared and alone in their first go at life and display typical animal behaviour of needing an ingroup.
