People are all the same

No matter how long I live I will never understand people. Just when I think I've met people who are not(or are less) predjudiced you turn around and WHAM! aww shit I'm so tired of all this crap. Why do people have to be so divisive? Why does one group always have to claim superiority? I know I'm rambling. Actually I'm more than a little depressed. Maybe I'm delusional. Maybe I'm full of self-loathing and self-pity. I really hate this.
