They hate Peterson so much because he advocates for self-responsibility, and the belief that some, or most, of the problems in your life are your own fault, and only you have the power to fix them. Redditors hate that, and want to be coddled. They want other people to deal with their problems on their behalf. Sure, Peterson's not the super-genius some of his hardcore fans make him out to be, but a friend of mine lent me 12 Rules For Life, and I liked it. Nothing mind blowing or revolutionary, but generally good advice. Despite his decades of actual experience as a clinical psychologist and university lecturer, these terminally online dorks think they know more than him because Contrapoints, or some other YouTuber, "debunked" things he's said, or, they point to his prior drug addiction as some kind of "gotcha!" despite advocating for better treatment of addicts. Really, those buckos just need to get off Reddit, and clean their goddamned rooms
