In the end personality is just how others perceive you, you can be very much mentally sound and still have a shitty personality from how people view your mannerisms, speech patterns, beliefs, etc. And a shit personality doesnt affect a normie or chad lmao, you can still find a girl.
Meanwhile being non-nt means you have a mental disorder that cucks you from seeing the world how others see it, you process and view things differently in different ways depending on which mental disorder you may have; it IS very detrimental to your personality, especially with something like autism or bpd which directly affects how well you socialise with other people, but that's all it is, a handicap.
You can very much still have others perceive you well even while being non-NT as long as you fraud that you view the world the same as others, that's why ntpill is law.
