Femdom doesn't make you a beta anon, it just opens you up to get meme'd on. Being an individual who refuses to grow or who is domineered over without it being a choice is being a beta.
It's like how preferring fruity or mixed drinks opens you to condescension even if you can out-drink all of those who mock you when it comes to drinking hard liquor straight and dry.
You're only a beta as long as you allow yourself to be consumed by lack of confidence, and also if you reach the point of unrealistic overconfidence that ends up only being socially detrimental. You do you anon, and be proud of your small victories. In the end only you can deign if your life has been satisfactory or not, it's from within not from without.
