I think the thing this shows mainly about Ms Abbot is that she is not the sharpest tool in the box, and that even in a draft if it were indeed that, if she were a bit more savvy, she would have made her point with more sensitivity and precision of language, even if the point was not valid. She is a bit thick, but is still way above a good number of the present Government's Ministers etc. A low bar.
I don't think what she said can be labelled "anti-semitic", it was not an attack upon Jews, just a poorly thought out (< if that took place) opinion, poorly expressed as well.
CRT of itself is not a bad thing of course, we need to examine all social, political, and legal structures and power distribution, focusing on the concept of race, and experiences of Racism, so that we can do something about it.
But as with all such things CRT can be misused.
It is working wonderfully well this story though, as another "Hey look ! a Dead Cat!" for the Tory Media, helping to take the Public's mind of the Narcissistic Bully Raab, who IS very thick.
