I think it has something to do with their perception of lack of respect. They have not gotten what they think is their fair share. Of course, your not divvied out respect, you earn it.
...And if you don’t get it, they perceive that you have not recognized that they deserve it. So it becomes their mission to drill that error into your worthless hide...Ahem...
Perhaps, they can’t accept the fact that, at this time, they don’t deserve it.
Suck it up Buttercup...
That may be true for some people, but this one is a doctor and white, which is generally regarded as pretty high up the food chain. I guess she believes that the white man is so evil that he won’t even extend his privilege to his mother, wife, and daughters. Maybe she knows that is not true and she feels guilty about it, and she is also guilty about her perceived responsibility for all of the other suffering among those not so privileged. “Progressivism” is a religion for these people, and a very self-righteous religion at that, and they are out to save the world.
