Yeah, the cartoon constructs a cherry-picked distortion of history, as well as current events.

As I was around in 71 I can tell you the Left didn't believe in toxic selfish individualism but in the social contract, and did believe in science and health outcomes including respect to others, so the cartoon is wrong. And those of us still on the Left would still say fuck The Establishment (ruling class and elites) and any American Left not deeply suspicious of anything that comes out your corrupt agencies like the CIA should do so. So, the picture is silly.
