"I'm going to teach you all the horrors of toxic masculinity by role-playing as badass, muscular, axe wielding, alpha male psychopaths, who do what they want, when they want, surrounded by women who necessarily know their place as subservient wives and daughters, in a patriarchal, totally unfair society!"
I do believe you all hit the mark saying this stuff is for self-loathing men. More specifically, men who are terrible at being men and therefore hate all things men. We don't live in a world where you're forced to be many things just by birth, but like if we did, and you were born into the basketball tribe and had to play basketball everyday... if you sucked at basketball and got dunked on, smacked around on pick plays, people talked trash in your face all day, you would despise basketball with a passion. They want a performative, public way to demonstrate their hatred of this thing they fail at.
