Why are people so racist?

Because history has showed us a distinct different in behaviors of minorities and non minorites. Non minorites have plenty of stereotypes as well..... there are also a lot of extrememly racist users here agains whites... for example, Dopest Ethipoian, Lovely Bunns, Equal Rights for a Black Brotha...... they talk so much crap on whites and say some pretty hurtful things.... don't think whites are some evil force and the rest of you are perfect..... cos you aren't and there is a huge amount of racism against whites.....
