I have yet to see any in the left describe it outside of the academics who formulated it. “Teaching the truth” is a vague and meaningless phrase.
"While critical race theorists do not all share the same beliefs, the basic tenets of CRT include that racism and disparate racial outcomes are the result of complex, changing and often subtle social and institutional dynamics rather than explicit and intentional prejudices on the part of individuals."
Tell me what is dangerous, anti-american or anti-white about that. It is basically just the truth.
