The problem is that the core argument that the article is making isn't whether or not a particular ideology is being taught. Instead it's saying that the ideology is being taught specifically in an exceedingly over the top manner, that the slightest disagreement carries the threat of life altering punishment, and that the situation is characteristic of elite education.

Without some sort of verifiable information it is difficult to determine if those arguments are valid. However, as the saying goes "extraordinary claims require extraordinary evidence".

>> I know for a fact this ideology is being pushed hard right now

And yet you have ironically failed to furnish evidence. OP rightly observes that the article is riddled with anonymous hearsay, and published by a tax exempt lobbying group. For those who choose to read comments first, here's a taste of what you have to look forward to in the article:

"says one of the fathers(...)'What he has a problem with is a movement that tells his children that America is a bad country and that they bear collective racial guilt. They are making my son feel like a racist because of the pigmentation of his skin' one mother says."

It’s a way of examining things. You know, critical thinking... https://www.edweek.org/leadership/opinion-no-critical-race-t...
