Right, the point is that the main article links only to the conspiracy theory and not that article. If it linked to that article people hearing e.g. Jordan Peterson use the term and then googling might be given a history of Marxist theory being applied to culture. Instead they see only that it’s an anti-Semitic right wing conspiracy theory. It’s made worse by the fact that “Marxist cultural analysis” is mentioned in the second paragraph on the “main” conspiracy page but not as a link.
Regardless of belief, and I’m by no means a right winger, do you not see how this will sway the opinion of anyone who googled the term cultural Marxism?
