whenever a group with distinquishing markings get in an advantageous position the first thing they do is consolidate by exclusion. Built in, reasoning is the only way to overcome the fear, but in the disadvantage zone, any overtures for inclusion is an immeadiate take advantage moment. You know it is not going to last so mine it for all it is worth. Again only reason can overcome inbred habits. We are a long way from becoming vulcans. If we recognise these traits and try to overcome them that is progress.
