So you quoted an opinion piece on what they think people mean when they say that rather than actually see the real definition.
Got it.
It is the "soft language" being used to sneak Critical Race Theory into the classroom. This is well documented. School administrators think that if they just name "Critical Race Theory" something else like "Equity" then they can claim "Oh, our system does not teach Critical Race Theory" while still promoting it under another name. This underhanded nonsense is not going to fly with parents. Simply changing the name and teaching the same CRT nonsense does not hide that it is still CRT.
