This is a real insight. In the South after the second civil war against the reconstruction regimes was over a cohort of people like this did emerge among white men. Their whole being seem to revolve around asserting dominance over negroes. Most, it is true, were so poor that their skin color was their only possession of value. A number were not, and other white people found them uncomfortable to be around. People like this often become consumed with evil as they make a racial zero sum game out of life. This woman is one of those individuals. Weaponizing numan relations is just one, although the most pervasive forms, of weaponizing all of the culture. In some ways this is a variant of the old communist saw of ‘politics in command’. Lawfare, weaponization of what in a free society should be as apolitical as possible (law enforcement, education, government administration, courts, popular culture) are all elements of the hydra of rage, viciousness, and eventually enslavement or elimination. This is very serious and goes far beyond individual boorishness. Carried far enough it produces either a conflict society or deadly violence.
The logical end of the “treat ‘em like crap to get ‘respect’” mentality is concentration camps, gulags, and genocide. See USSR, Third Reich, and PRC for egregious examples.
