why are some people racist just because we don't have the same skin color?

Question

why?

Answer 1

they were taught that their culture is better than all of the rest, and they become disdainful towards all other cultures. they are just crazy, and i guess aLittle insecure

Answer 2

I guess they have very low self esteem and need to find a way to make themselves feel better at the expense of someone else...it is a very sad and sick way to do so in my opinion however.
