Since I can't upvote @thrance's reply, I'll second it here: certainly complaints about postmodernism date to the 90s or earlier and fear of Marxism is as old as Marx (less sure about when "cultural Marxism" specifically became a scare-term of art)

I feel it's still ongoing, the reactionary elements are campaigning against anything circa modern (not modernist as in art but modern as organisation of society, so also anything that can be traced back to Enlightenment) and later, postmodern etc. They are actively destroying natural sciences too, which is a part of this effort. Feels like going back to feudalism.
