This is a completely separate issue, and worth its own attention.

It depends entirely how it's done.

Suppose you say the following: "People used to find reasons to divide people into different groups, and used it as an excuse for people in stronger 'groups' to be really mean to the people in 'weaker' groups. One of the worst cases was when the Europeans who came to North America, who were white, decided that having white skin made them the best, so it was okay to kill the people who already lived here and take their land, and capture people from Africa and bring them to North America to do their work for them. Of course, now we understand very clearly that what you look like is no excuse to be mean to others (some people understood it back then, too), and a lot of things that people did in the past were really really horrible. There are still a lot of problems today that are around because of how horrible things were in the past, and also because not everyone has managed to fully learn that how you look doesn't make you better and being better is no excuse for being mean."

Okay, no racism there.

Suppose you say the following: "All white people are racists. They stole and enslaved and did nothing of value except exploit other people. This country was designed by white people to allow them to exploit everyone else and make sure nobody else can succeed. It's very important to know what everyone's race is so you know what experiences they have had and if they are exploiting others or have been exploited."

This encourages overt racially bigotry against white people and implicitly suggests a racist attitude against everyone else, and is completely consistent with the tenets of CRT. (You also see this messaging in various places on Medium, if you want to see an expanded version where the points are argued for in more depth.)

Or your history curriculum could consist exclusively of cherry-picking the worst atrocities by white people against others, stressing the races of all involved, and leaving children to draw their on conclusions--which is that white people are ghastly, and everyone else is helpless.

This is intentionally phrased as an extreme to help illustrate the point. Typically the actual presentation is more modest. (But privilege exercises have happened, and they are approximately as bad as the extreme here.)

It is this trend that raise the legitimate ire of people who then are vulnerable to the gross exaggerations by the right regarding what CRT. The most effective lies contain a kernel of truth.

That there are lies about it doesn't mean that CRT is lovely and wonderful throughout. It has legitimate problems, too.
