The CMF was designed by people who don't like math and prioritize the "human experience" over physical reality. When you read through the CMF, you begin to see all sorts of hints that their ideology is inspired by Continental philosophies such as Marxism, Existentialism, and all of the other ways of thinking that find "facts" and "reality" offensive. For example, I lost count of how many times they mentioned the word "authenticity" in the CMF.

To sum up the whole CMF in my words, it's Critical Theory applied without critical thinking used. Proponents saw that minorities were struggling in math class, so they proposed a solution to handicap math classes. That's literally what CMF is. Proponents would rather see everyone fail than some people succeed. Especially if those some successful people are not minorities.

Why we should learn math from people who clearly have no respect for facts and reality in the first place is beyond me. Bertrand Russell, one of the founders of set theory, would have outright rejected most of the philosophy that inspired the CMF.
