Almost all of my male friends are "sexually active" and don't call people sluts, whores etc. Why do you talk about "sexual active" people as if its some rare breed of people that is hard to find? The vast majority of people are "sexually active." Maybe you should just hang around different people.
I have in mind the blue collar, jocks and rock band kids who are usually more honest and direct especially when you throw alcohol in the mix. YMMV.
That's just an example of an attitude people develop and my point is it is no way exclusive to "incels," in fact its an expression of the larger culture. Incels and their psychology are the creation of the culture. Of course, that culture is most pronounced in Hollywood.
Rogers derelict dad - worked in Hollywood. His friends - Hollywood kids. He grew up in the epicenter of Weinstein-land. Rogers could never fit meet their standards but his overall preoccupation with sex was the same as his peers.
Am I wrong here? What nobody wanted to admit is society based on sterile, fleeting relationships and porn is the real context and incels are an expression of the Id of the wider culture.
