Not sure you read that first link before posting it! It makes pretty much the same argument I was about to make. It also doesn't claim that white people are all racist, and points out that CRT doesn't claim this either.
The second article I don't really agree with, so perhaps I should've written "Almost nobody is saying that seriously" rather than writing "Nobody is doing that".
The third one I don't have a major objection to other than like the second, it defines "racism" in a way that I'm not sure is helpful. Western society is certainly set up in a racist way, but that doesn't make all white participants in it racist. At the very worst it perhaps makes them complicit, but I'm not sure that's helpful either. More helpful would be pointing out things that are wrong and how people can help to fix them, not trying to label them with anything. Personally I reserve the term "racist" (at least when using it about a person) for people who are actively racist, not just not anti-racist. In large part because it provokes reactions that don't lead to progress, even if you could make a reasonable case that it could be right like articles 2 and 3 try to.
"Why I'm no longer talking to white people about race" is a good book by the way.
