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'm not sure why you assume liberals are on the left. Communists and their friends like to say they are, when their other friends aren't saying "Liberals get the bullet too", but I'm not sure why I should trust a communist's view on anything.
If you're willing to work with the hypothesis that liberalism isn't left-wing, can you see why I'd make the points I'd made?
If by left-wing you mean overton window, then yes, I can accept it. It disgusts me with every fiber of my being to believe that the MSM, Democrats, Academia, and the filthy degenerates of the progressive wing have stripped the meaning and understanding of political leanings in this country. I don't believe marriage is the answer to every question regarding a family, but somehow I am considered right-wing via the overton window.
