Why are people more mean to ugly people (outside looks) than pretty people?

I understand precisely how you feel. The problem with human beings in general is that while we may have evolved from hominids to the homo sapien that is considered to be the avante-guarde version of the human, it still does not take away the fact that bigotry is inherent to the human persona. Human beings are genetically and psychologically hard-wired to behave in a specific fashion especially when it comes to physical appearance - it is the most unfortunate thing in the world, a disease if you will. Because if you take into consideration even the smartest individual on this little planet then that person must realize how truly ignorant he or she and how little of our universe or the nature of things do we really understand. Even so we deem ourselves fit to judge another and for that matter if a group of people were to condemn an individual then more people would join the accusers regardless of what the facts may state or who may actually be right or wrong - It's just one of those things about people that I absolutely hate and like Albert Einstein once said " Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." - That's just how life is - it's a goddam B&*H and if you expect it to be fair then no matter how talented you may actually be then your dead wrong....
