What I feel like a lot of people in the comment section here aren’t allowing us that the meme is criticizing the mainstream (I.e., propagandized) idea of the “radical left” and how “centrists” are in fact right wing but brainwashed into thinking they are moderate.

The “radical left” is just what a generation simmering in a fetid soup of Fox News mental decay calls common sense, basic human right policy. That’s what I read is the point of the comic.
