I beleive it's all in your head. I used to feel very self conscious in my CS classes about looking like a meathead, but I can't point to in instance during schooling or career where that feeling was confirmed by someone's actions/words.
In the manosphere subculture it is called getting "mogged" as in Alpha Male Other Guy and in forums where they speak freely it is an acknowledged phenomena.
I get the impression lots of other nerd types have a similar chip on their shoulders, whether from real trauma or imagined. As I have become more fit and more outgoing over the years, I find it's harder to connect with other nerds, perhaps because I don't share the same victimhood fantasy, or maybe I just seem unapproachable to them? I don't know, but I definitely feel more apprehension than when I was a fat guy with bad posture and ill fitting clothes.
I'm a nerd. I was bullied in school.
I was also fairly small and weak and non-sporty, so I was an easy target.
I also liked to talk and especially talk back to the bullies. Who knows, I might have even "psychologically" bullied other people using my wit and intelligence (several of my classmates complained to the teacher once that I would "insult" them which came as a total shock to me... was probably true but I wasn't doing it maliciously and wasn't consciously aware the impact it had on others).
It's really hard to generalize from 1 example.
I remember a lot of 'us'(the uncool kids, 'betas'(haha), nerds, dorks, dweebs, etc) being somewhat conflicted over the Columbine killings, because, while the perpetrators were absolute evil assholes, we understood why someone might feel justified in lashing out at the 'cool kids'(is that more acceptable than 'alpha'?).
There are definitely nerd bullies. Hell, my mom and uncle were exactly that in high school. They even used to taunt and make fun of my dad. Unfortunately for my mom, being a smart, sarcastic, cross-eyed nerd girl meant you had to sleep with the dorks, and behold, my family was born.
'Alpha' is a term of our times. Sorry, I don't define the language. Substitute 'cool kids' or 'socially elite' if it makes you feel better(assuming you want to feel better... maybe you enjoy being righteously indignant?).
I'm sure there are some people that feel that way, but when it comes to leadership, and other areas in life the truth is that your frame will give you 'instinctual' benefits. Not to mention with women.
Life isn't fair. But don't feel bad for the positive traits that you do have.
If you frequent such places, you will inevitably pick up the concepts they use, like you did with "mogging". Once you have the concepts in your brain, you will begin to pattern-match them in daily life - like you did with "mogging". It is exactly this acquisition of "new concepts with which to view the world" which is interesting. But once you start habitually viewing the world through a manosphere lens, you are on a slippery slope to becoming like them. Take a look - do you want that?
tl;dr meme exposure is dangerous and should not be taken lightly - we don't have the mental separation we think we do. This is not calling you out or anything, just a PSA to you and anyone else reading this thread - innocent curiosity is how people get radicalized!
