Marxism isn't an ideology.

By Marxist definition, no. In the traditional sense, a set of theories or philosophies held by a group or individual, often not epistemic, which informs a world view - very much an ideology.

Marx wouldn't have existed without liberal capitalism.

No shit. A critique of capitalism requires capitalism. What absolution does that provide though?

You're living under liberal capitalism where western people are actively being dispossessed of their own countries

That's a rw liberal meme lmao, in effort to separate liberalism from things it created. Not only is majority of radical liberalism built on liberal values and ideals, but much of it comes from civil rights act & affirmative action nonsense, including CRT.

all the atrocities done by people they dislike are in fact committed by ideologies/systems they dislike

Lets not ignore that globalism is actively being pushed by the left in hope of accelerated modernization. Arguably the easiest defense against that dispossession, nationalism, has by and large been a target of the left, including Marxists and neo-Marxists, since the French republicans. Progressivism was invariably influenced, and changed for the worse, by the Frankfurt school - refitting Marxian critiques towards culture as a whole. Developing Marx's rejection of logical positivism into an all out crusade by conflating it with inevitable fascism - a crusade which has negatively effected society and academia as a whole. The insistence on change instead of simple observational critique, coupled with the normalization, even romanticization of revolutionary action. How are these the sole responsibility of liberalism? Bastardized as it is, if current neoliberalism is the fault of liberalism, Marxism is at least as wanting for what it devolved into.

Contemporary social justice, as nonsensical and illogical as it is, has been weaponized towards the destruction of western culture. I survives and thrives on that rejection. Do you honestly believe all half of this bullshit would exist as it does now without critical theory, conflict theory, and where the rejection of objectivity is the norm in education and many fields of academia?

There's way more to learn about the system from anti-system people of all stripes, the only thing you're doing is limiting yourself and falling for liberal villains

Are utilized for. The absurdity of it is rather obvious, given the imperialist, exploitative, destructive empire we live under.

Presumptuous. I regard capitalism with no dogma, and I have more than a few bones to pick with liberalism - from classical to neoliberal. Capitalism was an improvement on feudalism. If it is to be supplanted, I simply ask for a superior alternative. Hailing from a very violent part of the world which romanticizes Marxism, and has been flirting with the worst elements of socialism for the past two decades, with a laundry list of historical failures in hand - failures that led to mass loss of life and further exploitation, I cannot in good conscience endorse or even tolerate the proposal of Marxism as a replacement. It is inflammatory, revolutionary, and fails in implementation.

While I appreciate your stance, not everyone is so reasonable as stop at the instructional value of an ideology.
