All you need to understand is fundamental logic.
If every organization known to be extremely liberal/progressive engages in self-flagellation for its racism, oppression towards minorities and white supremacy then the logical assumption is that these are the very people who cause racism, oppression towards minorities and white supremacy. I mean, it's the same down south, where cities and police forces which have been run by the Democrats for decades are self-admitted hotbeds of racism and must needs be purged and cleansed somehow. The same goes for American universities, museums, school boards, etc.
Why does no one ever ask why? Why is it an institution, organization and government controlled by the most liberal elements of society for a very long time claim to still be systemically racist and seek to grovel and apologize for their misdeeds?
You know why. Because they're all full of so much bullshit. It's a pantomime whereby they virtue signal by crying crocodile tears and making obsequious noises towards non-whites for their almost entirely non-existent racism. That was bad enough when it was confined to academia - though lately even there it's gotten worse in them lowering their requirements not only for admittance but lowering their teaching standards to accommodate lesser educated minorities.
But we've let this ludicrous faux racism mea culpa spread to every area of society. And while I can tolerate the eye-rollingly dumb sniveling confessions from various organizations and our woke prime minister it offends my sense of justice to see policy being implemented which sees hundreds of millions of dollars squandered on this crap. Likewise I heartily dislike hiring and promotion based on race, not to mention allotting government contracts and awards for the same reason. I also deeply dislike how it is deliberately dividing society along racial lines and pitting different identity groups against one another. I dislike how it causes resentment, suspicion and dislike both on the part of minorities who have been repeatedly told they are being oppressed and discriminated against through no fault of their own and in whites like myself who know damned well that's so much putrid, lying bullshit.
