CRT teaches people that racism is more inherent and prevalent in our institutions and is a systemic and structural problem, rather than an individual problem. Stop listening to clueless right wingers trying to tell you what it is.
Nothing biased? The people who came up with the 100 million figure, from the Black Book of Communism, literally admitted the main author of the book was obsessed with trying to arrive at that number and have distanced themselves from it. I think communists built a lot in many cases, especially in Spain in the 30s, and today in the Zapatistas and Rojava. Death is going to come from most revolutions. Don’t know why you would say communism is evil, except that some regimes became counter to socialistic goals.
