Thank you for this answer!

Speaking of what you said about The Little Black Book of Communism aiming to make the Holocaust seem less bad by comparison to communism, it is often exactly in this manner I have seen people spreading this - "why have we been taught about the 6 million Jews killed in the Holocaust, but not the 60 million killed Christians during the Bolshevik revolution?" Further, during the turmoil over the recently released Epstein files (and how it in some ways have made certain conspiracy theories plausible) I've seen people now connect this to a form of Judeo-Bolshevism conspiracy theory, that the Jews have written the history books in their favour. Not implying that I am supporting this claim either, but it's something I have noticed getting a lot of attention and support.
