They also seem incredibly narcissistic too. I really don't think it's healthy to think you are 100% perfect and a blessing to the human race. I'd wager nobody is. And that's okay. Acknowledging you have flaws is how you fucking fix them. If you ignore them or convince yourself they aren't flaws you'll never improve. In fact you'll only get worse.  Could you imagine if functioning members of society had that attitude? Like what if you were a civil engineer and someone told you your design wouldn't work and you were just like "Fuck you my design is perfect and beautiful and flawless. A real man wouldn't ask my design to change!"
