At the same time, not many people have the ability to just say insane things in public for not having enough necessary amount of narcissism. My sister thinks it's my actual superpower.

The cue to see if it's the case of being disordered is looking for what causes them shame, and how they MASK it. Because normal people make peace with their shortcomings therefore not to hide it. Their ability to make friends and have stable relationships is the proof of how they can accept reality. NOT the privilege of being disordered-free.

But for people who feel they are not valued enough, they will mask the shame by fighting for the other gender to stop toxic masculinity. People who feel they are not courageous enough, they will mask their shame by cheering for other people to do more violent revolutions.

Yes, maybe toxic masculinity is a thing, and sometimes violent revolutions are necessary. Which is why someone's views about the external world alone say very little, without we also having their confessions about themselves.
