I agree.
I just don't think the right's misunderstanding of the left is any more egregious than vice-versa. They're both sorta right and grasping at something but it's out of their frame of reference. To be fair members of each side would also struggle to identify their own fault and battlelines. I think grouping people is hard, you need to both be a somewhat insider (or at least lurker) AND need to be analytically inclined and alienated enough to actually do live sociology on your own tribe. It's a hard thing and I don't wanna nitpick or dunk on people because it's too easy to. And there is something important they're grasping at with these terms, on all sides. There's some real thing and everyone who adopts it sorta understands what it is, which is why they adopt it in the first place, they finally have a way to talk about something that previously had no name. Betty Friedan, of all people, speaks quite a bit on this in Feminine Mystique, what a breakthrough it is just to be able to put a word on your adversary. This is why Ghostbusters is a better metaphor than the Matrix.
