I'm still on the fence about that. When I watch some media from the 90s or 80s that would be considered "Progressive" at the time (example: Sliders), I find I mostly agree with it. Then there's others that are Progressive but clearly Marxist idealism (example ST:TNG).

Not all that long ago, the ACLU defended Nazis. They were a principled organisation at one point.

I don't know, maybe Progressivism itself was infected by Marxism early on like many subcultures have been recently.
