I call you stupid because you try to use stupid reasons to justify the simple fact that you prejudge people based on their race, which is something that has no justification whatsoever. You are part of the problem, your attitude perpetuates the racism in both directions and you are too stupid to see that. If you kept your mouth shut about it instead of bragging about it perhaps you wouldn't be called stupid so often. In simple terms, don't do (or say) stupid things that cause others to say you're stupid. If you're racist and can't/won't change then keep it to yourself and keep it YOUR problem.
