I agree with much of what you wrote, but the highlighted statement shows a complete misunderstanding of how this worked in American. The Woke nonsense started on college or university campuses, yes, promulgated by Marxist leaning professors of the humanities and first taken up by POC, people of color there through affirmative action admissions, i.e. AOC and other members of the "Squad", who, having difficulty with the curricula, often remain for five and six years, and are subsidized by the government. It then spread to the larger part of the student body. They intimidated the administration and other professors to go along with their demands. I watched it all unfold; the classics banned, the teaching of history bastardized, professors who spoke up fired or "cancelled". Those who spoke up about it, including Razib Khan, and people on the right, were told it was limited to the colleges and was just post adolescent stupidity. Instead, it spread from the campuses with graduating students who worked for the "New Left", including in elementary and secondary schools. The BLM movement both partly grew out of it and fueled it. The trans mania was another outgrowth of it, destroying women's sports when so many of us fought to get our daughters equal access for federal funds for girls' teams. Now we're at the point twelve year olds can proclaim a sexual "identity" at odds with their genitalia and chromosomes being given drugs to stop puberty, and girls having their breasts lopped off.
This is no chimera. People have been "cancelled"; their livelihoods affected, and as per the above, their bodies irreparably damaged.
The corporations were among the last to be affected, certainly after the education system and government organs and the media. Have Europeans not noticed the bizarre output from Hollywood? The corporations responded as they have always done: they caved in terms of messaging, i.e. ads, and they paid "hush money" to these organizations, like BLM, as they had paid "hush money" to Jesse Jackson and all the other hucksters agitating in the name of equality but just seeking to line their pockets.
