I don't care if it's a "moderate", a "rational" or whatever prefixes do you have for these leftists who says they don't support the Marxist shenanigans in academia or the occurring Cultural Revolution happening all over the West over the past decade, they are lying. And you believing their lies that they're against it while not doing anything to oppose it only enables these primordial evil that's going on in the world today.
In short: "Don't believe their lies." Lying is as innate to them as they live.
I mean, they're here shitposting and claiming to be left. So, yes? It may not be a big demographic but lefties willing to tell Marxists to fuck off is a real one.
The biggest problem is lefties who claim to be against the Cultural Revolution style bullshit is that many of them have a history of being fickle and easily distracted. The Chris Rayguns of the world, who let the veil get lowered back down on them by their friends and start believing there's a boogieman in the closet again, and suddenly they need to stop calling out the black-clad street killers so they can all band together and stop the boogieman.
