Only place it is taught is law school. It's a legal concept, that racial discrimination is not about bad people or bad intentions but that laws and regulations created and reinforce racial discrimination. It's not even startling. And it's true.
A Hitler loving Trumper doesn't want anyone to learn about racism, what a shock.
Critical race theory is 2021 version of Sharia law. Remember when all those state legislatures were banning Sharia law? No one was proposing Sharia law be implemented in the US and none of these legislators even knew what was in Sharia law. It was just whip up fear of scary brown people so white folks will vote for Republicans to protect them. No one is teaching critical race theory in kindergarten, but all of a sudden Fox and other right wing media are running literally thousands of stories.
But college classes on race in American history are being cancelled (is that cancel culture?) Idaho seriously proposed teachers wear body cams so they could be monitored. States are prohibiting saying slave owners were bad people.
