Very true - a ton of ambiguity here. I guess one of the debates would be just that, what is meant by marxist. I would say anyone who abides by an ideology that is (directly? indirectly?) in compliance with discourse from Marx or other marxists, is a marxist. Since there is a spectrum or variety of positions that would thus qualify, would some of them pass as right wing - and which ones?
And I'm starting to wonder if marxism isn't limited to anti-capitalism. Granted, it could entail a very generalized and abstract interpretation of his work, but I wouldn't consider such an interpretation to be unreasonable, especially considering how abstract he got (from what I've read).
This is a pivotal debate for me, and one that greatly confounds me, especially now that woke capitalism promises (or threatens) to become even more of a reality.
I think opposing capitalism, radically, means opposing the way matter and intelligence evolves, universally. That said, there is a ton of disagreeable ethical baggage thrown onto most conceptions of capitalism, that that baggage is more than likely non-essential. It's like being allergic to the air around you - which seems to shed a light on (what appears to me to be) the general impotence of the Marxist project since, what, neoliberalism?
So a "pro-capitalist" marxism would shift its frame of reference from the setting in which capitalism contends with other potential economic -isms, to the setting in which capitalism is itself the stage on which contend different flavors of capitalism, of which there are an infinite variety. This doesn't necessarily preclude the eventual emergence of communism, but it does add a whole other gauntlet to run before we get there.
Maybe I'm drinking the "tech-bro" koolaid, but it seems like communism, proper, is only possible if there is some kind of superhuman intelligence that is governing us, one whose bias is virtually undetectable, and next to objective.
Whether that amounts to a utopia or a dystopia, depends on whether or not we continue to indulge our allergy to capitalism. I think anti-capitalism, radically, is a denial of the cosmos. That said, for most people "anti-capitalism" simply means an opposition to the ethical murkiness of capitalism, which is far more reasonable and far less radical than the anti-capitalism I have in mind.
In fact, I might even up the ante and argue that any radical anti-bigotry needs to overcome its allergy/phobia of capitalism, in order to start making the next wave of progress.
