For example, a white Appalachian coal miner and a black Ivy League professor have a power disparity based on income, education, and social class.
But the "prejudice + power" crowd will have you believe that the coal miner's membership in the elusive all-powerful "white people" monolith gives him more social cache´ (hence power) than the professor. That's because the professor's membership in the elusive "black people" monolith puts him near the top of the marginalized intersectional hierarchy.
Any rational person who isn't obsessed with the phenotypical categorization of individuals (aka a bigot) will reject this notion - recognizing the professor's freedom/power relative to the coal miner.
People are individuals (not groups) with complicated lives and experiences.
To reduce ALL "black people" to marginalized victims is the soft bigotry of low expectations. But worse, to elevate all "white people" above all "black people" is a vile and tacit view that all "white people" are the necessary saviors of all "black people". This kind of twisted illiberal thinking permanently infantilizes all "black people".
