as for racism
they keep redefining it to suit whatever the narrative needs.
it went from literally segregating privileges on the basis of race, to any acknowledgement of racial differences and possible superiority of one over another, to now just meaning "oh the outcomes aren't perfectly balanced, that must mean the process was racist somehow."
its basically meaningless now to the point literally everyone is a racist, if only because unless you have a specific form of brain damage you will always bias towards your native race over others. at least in studies where they show you pictures of people and measure the time it takes to compliment the photos, everyone has a micro-bias towards their "tribe." which is part of a survival mechanism so it's not going anywhere any time soon.
its kind of like how when they do psych tests they find that women "objectify" other women the same amount men do, but men still get blamed for being "sexist."
never really found the stereotype thing to be harmful unless you're explicitly being a jerk about it.
