And it is actually millennial betas who are finally raising a sort of a rebellion against feminism these days
See, I was at least 50% agreeing with you until you said this. But this is absolutely wrong. There's nothing wrong with skinny guys, since by definition it only means they don't go to a gym consistently or eat a large enough calorie surplus to gain mass if they do work out.
Like, I'm fairly skinny and I have a testosterone level that's borderline higher than the "safe" level. It would have been considered average in 1950, but now it's considered too high with the "improved" standards. My arms aren't pencils, as I have a fairly physically demanding job and am naturally acceptably strong, but nobody would look at me and think I work out.
However, as a whole the millenial beta generation is lost. And I don't like the beta terminology since it's not as clear-cut as alpha/beta, but the generation is lost regardless. It's simply failing to materialize. The men and women who were supposed to become strong members of society are still mentally children, and what's more, they're trash on every level. Unintelligent, addicted to following authority figures, they worship women in ways they don't even realize, they live for drugs or alcohol, and they do all of this because they don't even have a basic concept of honor or self-respect. They're servile in every sense of the word.
Don't get me wrong- baby boomers set the stage for this. They perverted masculinity by making it more about being an idiot and worshiping women than about being strong and noble. Baby boomers were the first generation in history that accepted this shit, and it's because they had such easy lives living in the golden age of American history (and the age in which corruption in the government and media began, due to the lowkey communists that we let in from Europe, who were ostensibly refugees from the Nazis). But it's only gotten worse since then.
The only redeeming feature of this generation is that they're such failures, their children will probably grow up to be hardline far-right extremists, traumatized by the degeneracy of their parents.
