The reality that I don't think people want to stare straight in the face is that our human world is rife with interlocking systems of social/political hierarchies and that fractal network of power and abuse fosters conditions which encourages all groups of people to punch downward in order to gain power.
That includes marginalized groups of people, too.
One of the routes into power and mitigating exposure to oppression is to embrace the system's hierarchy and promulgate abuse downward.
