Being a religious Marxist is contradictory, so his stance is, but it's worth mentioning that there are non-Marxist religious communists whose stances are much more coherent, even if they are still wrong and in reality we need a materialist understanding of the world to not kneecap any ability to engage with our conditions.

Yes that's the issue. Eventually the contradictions will compromise the Marxism.

Being a subject of capitalism isn't the same as being a liberal, just like being subjects of feudalism didn't prevent those liberals revolting against it from being liberals.

So the thing is even by not being an active supporter of the capitalist system you still massively benefit from it if you live in the imperial core. So I just view that as being an involuntary capitalist subject.
