I think it's safe to say that racism is only a matter of ignorance and immaturity. If you only took the time to realize that people are people regardless of what color their skin is. It would be better to judge a person by their personality than by the color of your skin. I wouldn't waste your time trying to argue the pros and cons of every race because I guess in the end it's just your opinion, and everyone is entitled to one. No one is going to change their outlook just because you tell a joke or some biased "fact". But If it helps you sleep go right along...
