What my nephew did is called projection. It's the first psychological defense children engage in. It's the first one adults use, too. Most don't even know they're doing it.
Projection is when people blame their problems on other people. Sometimes it's called scapegoating. The late psychiatrist M. Scott Peck called scapegoating "the genesis of evil" in the world. He's right.
Whatever word is used, they mean the same thing: I'm good and and you're bad. Because you're bad, you're the cause of my problems, so you must be insulted, mocked, humiliated, denigrated, devalued, ostracized, and at worst, killed.
I see projection all the time among what I call the Lost Boys of the Manosphere. They're the ones who think Alphas, Betas, Gammas, Sigmas, Omegas really exist.
Of those who really think they exist, here is what happens (I predicted this): the insecure ones are going to insist they are Alphas/Sigmas. Anyone who disagrees with these silly terms is going to be insulted as an Omega, Gamma, Beta. It's happened to me.
I'll repeat again: that's what scapegoating/projection is. I am good and you are bad. I will idealize myself and devalue you.
It's based on our inborn narcissism: either idealized or devalued. Grandiosity covering up insecurity. Those who claim they are Alpha/Sigma and scapegoat those who disagree with those terms are themselves terrified that they are the Gammas, Betas and Omegas of the world. They're projecting their own "badness" onto other people. Onto men, and onto women.
They are using grandiosity to cover up their feelings of humiliation and insecurity.
If you want to use those terms, every man is simultaneously an Alpha, a Beta, a Gamma, a Sigma, and an Omega. That's what I am, as is every man.
The Manosphere is a needed, in fact inevitable, reaction to the evils of feminism, which itself tries to humiliate and devalue men. And in fact has. But it's making a detour into some bad places.
Some of those in the Manosphere are doing the same thing to women that women have done to them: you are loveless, greedy, rationalizing, gold-digging whores with no self-awareness whatsoever, and you are the cause of my and society's problems. You can't devalue women much more than that. They're devaluing women and blaming their problems on them so they can make themselves feel better ("I am an Alpha! I am a Sigma! You're a gold-digger and a whore!").
These Manosphere concepts are the mirror image of feminist concepts such "patriarchy," "oppression," "sexism," "lookism," ad infinitum, ad nauseum. They're just as deluded and just as dangerous.
The ancient Greeks, even though at times utter shitheads, were terrifyingly intelligent. They understood what Hubris is: thinking way too much of yourself until you lose your sense of what's right and wrong. They understood the opposite of it: Sophrosyne, or understanding yourself and realistically assessing yourself and your strengths and weaknesses. Often it's described as "Nothing in excess" and "Know thyself."
And you know what? Almost all the people in the Manosphere know of the concepts of Alpha, Beta, etc. but don't have a clue about Hubris and Sophrosyne. They don't have a clue as to what they are really doing.
