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.
Even after Gamergate I was in that "moderate" kind of position for a long time. I thought that maybe if the other side can't be convinced then at least the onlookers mostly could be. Instead, they will just blindly follow whoever is in power.
