Animals are territorial because they are animals incapable of rational thought and logic, they don't breed outside their pack because it is against their nature, only with humans do you find a zebra breeding with a tiger, we also have to meddle in things. I wouldn't say nor is it logical to say they exhibit racial tendencies, racism is a human malady based out of fear and lack of self esteem, I also miss WhiteyBlackman hope he can find his way here.
