"Cultural Marxism" is a shibboleth used in far-right white nationalist circles to mean "not racist". It's typically paired with claims that "cultural Marxism" is a "Jewish plot" to cause "white genocide".
Sorry, but you're not going to be able to tag somebody like me with the alt-right label. I'm none of those things. The point is that the BBC isn't only disliked by Indian nationalists. That's what I was responding to.
BBC is fine for left-leaning Anglosphere types, but it's not very broad in terms of the views covered.
