I can understand that that's a possible (even literal) interpretation of the phrase cultural Marxism. However the Wikipedia page for cultural Marxism is heavily referenced and suggests a scholarly consensus that the term is used differently. Now, it could be that the scholarly consensus is wrong; but that's not the fault of Wikipedia. It could be that Wikipedia is cherry-picking or misrepresenting articles or scholarly sources; after an admittedly brief look, I don't think it's misrepresenting them, and after some searching I couldn't see very many scholarly articles with the opposing view. I did find some articles on websites with a right-wing slant which attack the Wikipedia entry, but that's to be expected even if the scholarly consensus were correct.
