Why do we humans discriminate and turn racists against our fellow men and women all over the world?

I agree with you wholeheartedly, however, yahoo answers may not be the right place to share this kind of opinion. It's just a place where a bunch of dumb teenage girls can get online and ask "Does he like me?" over and over again. You should take that awesome speech to a school parent group or something. It was awesome, but on yahoo answers it may not have as big of an impact on people.
