Not technically a behavior, but - having hurt feelings over other people expressing their negative opinion about myself.

Like, say someone tells me I look bad of that I acted badly or whatever. I see three options:

1. They're right, so it's a good thing they told me.
2. They're mistaken, so it doesn't really matter (though the fact some people might think that way is still valid information)
3. They're being mean, in which case I don't really care about what they say.

I guess it's some defense mechanism? I can see how that would work with people prone to narcissism, but having ones feeling hurt over things like that seems normalized in (most?) societies.

Oh, also religion. People believe in an all powerful being that personally cares about every person in the world, but is unwilling to reveal itself? Despite having zero corroborating evidence? And he's responsible for every good thing that happens to me therefore I should see that as proof it exists and believe more, but if something bad happens that's because I didn't believe hard enough and should therefore believe more? And you're sure about that and don't see how that might be purely because this answers a psychological and social need? I understand I'm exaggerating a bit, and no offense to religious people, but... I don't get it.
