The controversy about the Cultural Marxism page is what made me give up on Wikipedia completely. It's a real thing, Horkheimer and Adorno wrote a whole book about it, I own the book, I've read the book, and anyone can buy and read the book off Amazon to see what they were talking about. It's all there, they weren't joking about it, and it's a very real thing. However, if you cited the book this stuff comes from (Dialectic of Enlightenment) then Wikipedia editors would remove it for being "primary research." Literally quoting the book that the concept comes from and what the creators of the idea said about it was against their rules.
Of course, there is nothing wrong with citing the concept or discussing it. This was all an attempt at gaslighting via rules lawyering because people online were wise to the games of modern communists.
