"History is written by the victors."
That's an old saying, but the implication is clear: just because that's the history you've always read and believed, that doesn't automatically mean it's completely grounded in fact.
I remember in high school in the Deep South, I was taught that the Civil War was all about state's rights, and not so much about slavery. Then the internet comes along, I read Mississippi's articles of secession, and I see just how much I hadn't been taught.
Is "Critical Theory" perfectly factual? No. But it *does* include a great deal of verified fact pertinent to our nation's history that we had never known.
Oh, and one more thing. "The totalitarian Left" is an uncalled-for ad hominem attack that detracts from the effectiveness of your writing, especially given that ensuring that *all* people have *equal* opportunity is a liberal tenet. Witness the voting laws that have been passed in red states since the VRA was gutted by SCOTUS...laws that *ensure* fewer polling places (and hours-long lines) in urban areas, but no such restrictions in rural areas. And then they pass laws to ensure that no one can give water or food to someone standing in those hours-long lines in urban areas.
In other words, there is a part of the American electorate that wants totalitarianism. It's the same side that embraced authoritarianism (which, after all, is a synonym for totalitarianism).
