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?
It's real simple in politics - does this have any chance of bringing men and women together into getting married and having kids? If yes, then they attack it..
The "reasons" after that are just tools to attack with.
Regular people dislike PUA because they prefer the illusion that women's dating choices are moral and just and PUA interferes with that.
The press also tends to depict groups using their worst members, and the worst PUA's are definitely extremely annoying.
