there are plenty of text out there:
Critical Race Theory (Third Edition): An Introduction and
Critical Race Theory: The Key Writings That Formed the Movement These are by actual CRT theorists.
the basics are not difficult to find:
Recognition that race is not biologically real but is socially constructed and socially significant. It recognizes that science (as demonstrated in the Human Genome Project) refutes the idea of biological racial differences. According to scholars Richard Delgado and Jean Stefancic, race is the product of social thought and is not connected to biological reality.
Racism is a normal feature of society and is embedded within systems and institutions of America, like the legal system, and the financial system.
There are two forms of racism, one popularly envisioned a race based violence, the KKK, overt violence and cross burning. The second invilvles the collective attitudes and super situations of all members of society CRT rejects the popular understandings about racism, such as arguments that confine racism to a few “bad apples.” CRT recognizes that racism is codified in law, embedded in structures, and woven into public policy. CRT rejects claims of meritocracy or “colorblindness.” CRT recognizes that it is the systemic nature of racism that bears primary responsibility for reproducing racial inequality.
These inequities re held in place by legal statue, they can include racial profiling, inequities in the legal system and unwritten rules in financial systems
The only way do deal with this second form is through open and honest conversations
That is CRT in a nutshell
