Proper Marxist class analysis is not identity politics. That's precisely the differentiator between "identity" politics (politics centering personal identities and innate personal qualities) and Marxist class politics (politics centering class relationships, i.e. working- versus ownership-classes). And it's somewhere that predominately-Western leftists have completely lost the plot, starting at least as far back as the 1960's. To put the distinction another way - class politics is about what's real (the real relations between people and property, for instance), while identity politics is about what's in people's heads (their personal notions of identity). IMO, at least coming at it from a left perspective, it's really important not to lump these together like so many damn "leftists" do. And there is of course a lot of grey area (LGB rights being a notable one because there is a lot of overlap), but the TRA narrative always focuses on identity (i.e. "in the head") politics because that's the only place it can possibly exist. I don't know your politics, but I think there's a very large contingent of people who think "Idpol -> Marxism -> Leftism" is the only way, because so many online leftists consider that the truth. But it's certainly not the only interpretation, and because identity-based politics focuses on the small minutiae of identity vs. the very broad applicability of class, it's one that's actually counter-productive to actual material benefits for working people and one that helps the ownership class. As an example, think of all the resources directed to helping "trans women of colour" that would actually help everybody if implemented universally, but because of the ideological fracturing of identities, the focus is always on oppression olympics and small marginal gains for some identity classes at the expense of others.

As for Vaush, I just know he's a... controversial figure among terminally-online leftists, they tend to love his content sometimes, but then he'll say or do something "problematic" and he gets "cancelled" for a week and then it goes back to normal. My own sanity is too fragile to actually follow that nonsense in any depth.
