Stephen Crowder, for all his flaws, talks about this actually. He talks about it being societal and cultural shift to make *any* semblance of comradery with another man to be seen as "gay" and therefore something to avoid.
Crowder's vision is limited though, unsurprisingly. I know what this is about, its about eliminating familial and close bonds between human beings.
Fuck who you want, don't bother getting to know anybody, you don't wanna be too close because its gay or it'll hurt you or you'll get accused of things, whatever you fucking do don't know anybody.
A population is easier to move, easier to control, and easier to manipulate when they have been reduced to one-four or so personality templates with no bonds between eachother or to anything around them.
This is also why they want to see Traditionalism and Tradition destroyed. No more holidays, no more history, no more practices, no more gods, just one fucking mass of cunts who don't know who they are, where they are, who they used to be, and worst of all they won't fucking WANT to know.
