We need to do more to end the lie of cultural marxism

I think you're missing the point I'm making. I'm not saying that it is "Marxism" in the sense that you are: it is an 'off-shoot', so to speak. Western Marxism has a "common ancestor" in Marxist ideology. If you are ideologically opposed to them, that is besides the point to the similarities, in terms of worker's plights (only dealing with it in different ways and approaching the issue from with different viewpoints than yours).
Sure, but that doesn't mean it isn't a branch of Marxist thought. For reference: britannica.com/topic/Marxism/Variants-of-Marxism

Never claimed such a thing.
Well, that's not honest. They didn't "move away" from it, they approached the issue at a different angle. Again, it is not uncommon for a set of beliefs to adapt with respect to dynamic environments/over time, and simply because you ideologically reject the revised set of beliefs does not mean that they are not influenced by some original movement.
Are you the same person who called Adorno a 'proto-fascist'? If so, respond to the point I made about your judgement on why you can call him a 'proto-fascist'.
In what way?
According to? If you mean that they are not Marxists like the individuals you agree with, then that's what I've been saying this entire time. Doesn't mean they don't constitute a revised variant of Marxism.
Do you understand how dilution works? You will still have 100 mL of vodka, so when you finish the 6.15 L of vodka/coke, you will still consume 100 mL, it will just be watered down and you'll have to go to the bathroom. A more apt analogy would be to compare the divide between paleo-conservatives and neo-conservatives. Both are still 'conservative' (in that they follow a conservative set of principles), they just disagree on how to reach common goals.

postmodern liberals are not commies, they are capitalists who have nothing close to the same goals as communism. They think Marx was another dead white male and his historical theories are eurocentric

I never called them Communist. Stop putting words in my mouth.
If you ideologically disagree with their revised approach and methodology, that's fine. It doesn't mean that Western Marxism isn't a variant of Marxism. I've already addressed the point on societal/cultural changes when approaching a new set of principles over time. I'm not calling neo-libs equivalent to libs, I'm examining the common ancestry in both viewpoints.

For example, on the same link I referenced above on Maoism:

It continues within the link above. Like I said before, the societal/cultural environment and context in which the principles are applied may have just cause to revise said beliefs in certain ways while still maintaining the analogous nature (with respect to the 'original set of beliefs'). Maoism isn't not a variant of Marxism just because you disagree with their revised application for the same reason that Western Marxism cannot be dismissed as a variant of Marxism.

That's great, I'm not berating Marx's ideas: they were. My point has already been stated, quite clearly if I might say.

Targeting hardened ideological opponents for conversion is a waste of time and resources.

I've demonstrated my arguments clearly and presented supporting evidence for the claims precisely because it's common knowledge. You're more than welcome to address what reasonable issues you have with the three main points I've raised. At a cursory glance, Duke's link also discusses the main issue I raised: the derivatives of political correctness and its usage as a tool first developed by Western Marxists.

source?

Probably retarded idea but asking doesn't hurt.

Start and update a large online FAQ/question database elucidating common misconceptions of leftism or bullshit peddled by reactionaries regarding leftism. Question would be polled,and answers would be "crowdsourced" to avoid misinformation or bias, in a cycling thread for example.

So when you run into some dumbass in the wild spouting idiocy, instead of getting into the argument for the millionth time or just plain cussing at them, just politely send the link. If they have any interest in dialogue, they'll get back to you, if they don't you just saved youself a lot of time.

It sounds good in theory but probably almost pointless in practice. People who have any intention to change their mind and inform themselves already have almost limitless options. People who don't will look into alternative facts.
