But that "cultural marxism" label might be neither very cultural nor particularly marxist does not mean that what it labels isn't for the most part senseless bunk either. Oh, and marxism does happen to be more popular in academia than it deserves, too.
What does a simple idea like "stop treating women as though they were all idiots" have to do with any particular culture? If you don't understand the difference between "stop insulting your female colleagues" and Marxist economics or politics, obviously the problem is that there is not too much, but too little Marxism being taught in academia.
Really, the sooner marxism is completely forgotten the better. And what is usually called "cultural marxism" would make Marx and any classic marxist spin in their graves.
I would like to see some references of which groups or individuals, exactly, "treat women as though they were all idiots". Makes for a nice strawman but not anything that Strumia claimed, is it?
