One of my clients and good friends is a total follower. Hates to make plans, just wants to show up. Never picks the restaurant, never started the conversation with the girls when he was single, etc. A very wait and see kind of guy. Just a super chill dude. Gives people the benefit of the doubt, often. The fry guys on this board would call him a beta over and over, would probably ride him mercilessly.
Until he used one of his four black belts to crush their larynx's before he got on his private jet with his model wife and flew away.
Be careful who and how you judge, I say.
You know who goes on and on about alphas and betas on message boards? People who are unsure of themselves.
