...Is that supposed to be parody?
In my experience there are two kinds of brocialists. Type one uses their outwardly progressive values to woo women, particularly in the public realm of social media, while secretly maintaining their non-progressive values. Type two views women as expendable objects and treats them poorly to hide their insecurities. By pretending to the world, and probably themselves, that they're all about liberating the underdog, they get an angelic reputation while staying snuggled into dominant patriarchal structures. In both cases it's the combination of arrogance, yet empathy for everyone and everything—on their terms—that's the true signifier of brocialism.
Uh... Yeah, that does sound like dick behaviour but isn't that just your garden variety "person pretending to be something they are not so that they get to fuck someone" rather than merely a socialist problem?
And I might be too sex-positive or something but complaining about bikini-models sounds like slut-shaming. Give the women right to dress the way they want, having a career as a bikini-model (or God forbid a porn star) is not wrong in itself and neither is it wrong for people to enjoy them.
I do agree with the complaint about some dude sleeping with a lot of women while pretending to be monogamous. Then again I am also acquainted with a few people from polygamous relationships so in my opinion there's nothing wrong with sleeping around as long as everyone is aware of the circumstances.
