I was thinking about why some people hate the pickup artist community, and that the general consensus is that the regressive left and gender criticals hate them because they believe they incite sex harassment, while incel community and some sections of the manosphere hate them because their advice is considered garbage/not universal/fullproof enough.
Did I pretty much hit the nail on the head?
I'd imagine PUA are hated because they cannot be shamed into control. If something can not be controlled then it must be destroyed.
