Now come on. I'll answer the points you raise here, but I asked a very straightforward question: isn't this getting pretty close to CRT?

You claimed that CRT wasn't being taught. Back up your assertion first, or explicitly drop it, but whether or not you can understand American history without this kind of analysis has no bearing on whether CRT was where this kind of analysis was developed and promoted, or whether teaching it can reasonably be characterized as "teaching CRT".
