Confidence is a flaw when you're sub5, just like everything else
Unjustified confidence is almost a weakness in any case. Emboldened stupidity. Baseless Confidence.
Baseless Arrogance is basically that in a sense because you think you're of value pretentiously. Though I suppose arrogance is about affirmation about yourself in relation to the competition. It's not necessarily arrogant if you base confidence in general on being good at pottery or gardening (but it would be stupid to base your entire self opinion on those things alone, and have your brain/ self belief be totally numb when you're incel 3/10). Though I guess you could if that makes you feel you have a feeling of self importance over others, and are innately more qualified in life than other people. A sort of confidence that reeks around rank and order relation, and sees oneself atop that rank and order.
Arrogance is about feeling you can stride over other people, irrespective of what may come your way. And that because you're superior to other people you're innately more deserving/ capable by your traits. And you think those traits/ abilities can back up your feeling of superiority/ conditions of arrogance over the whole of the world. Mankind's mindsets are predicated around a uniformity of rationality. I'd be hard pressed to see someone who bases it off... gardening and pottery alone... and not being chad.
Sometimes self belief has nothing to do with your rank and order. Sometimes self belief can be baseless and put forth as an ideal for a person to believe that them living boldly no matter the circumstances will work. There is a little bit of faith in that, as a rational human being can't possible have a believable confidence when they're 5'2 bald indian.
And, having pinterest inspiration esque quotes fuel your worldview is whitepilled stupidity. Being truly confident/ independent from the position you're in as a noble ideal is also very stupid. That's called fairymerry confidence.
Flaunting Arrogance is where you feel you're above the system and can prevail in anyway, and thus put it to the external (bad strategic position). Abstract Arrogance is where you keep it to yourself and don't let anyone know about it.
Pragmatic confidence is what you should really have. When you're in a good position. It's just that most hierarchical minded girls will need the guy to have self affirmation/ belief. Insecurity, although valuable, is an indicator of inferiority. You need to be formidable in almost every position, or at least seem/ appear you feel it, but most of all seem/ appear that you ARE formidable. But at the very lowest you can't show weakness. You need high T vibe value.
