There is no primary, middle or high school in America teaching CRT. Parents are angry that their white children are being taught US history which includes slavery, and the Indian Wars, all of which harmed the non-white victims of the US government. They don't want their precious snowflakes to hear anything BAD about white Americans. It's bad for their fragile self-esteem.
Unless Americans face their history and the results of systemic racism, it's condemned to continue to repeat the mistakes of the past. Like assuming that crime and poverty are caused by racial inferiority, and not racism and lack of opportunity.
