Is it normal that i'm not bothered by meanness?

You are very right. This is exactly why i think we should not just dismiss the mean people as assholes to be avoided. They do have insecurities and they need companionship just like everyone else. It's hard to get past their wall of negativity sometimes to see that they are actually a good person, or that they are actually being helpful (in the case of tough love), our that they just need help. And while these mean people are simply defending their insecurities, much of the rest of the world are simply avoiding their own insecurities when they dismiss the mean people. And the problem only gets worse when we become resentful toward them.

I didn't realize how multifaceted this issue was because there really is a lot of anger and meanness in the world. I don't think anyone should tolerate abuse or manipulation and i'm not trying to promote bullying or anything. I am just totally against anyone being singled out and made to feel like a lesser person, whether it be the mean person or the person receiving the meanness.
