Different cultures have different methods for structure of their societies. That one culture of people see the utility in overpowering another culture of people simply because they could and can is more an infected psychopathy about those doing the overpowering. The idea of conquerer or manifest destiny against those who are of our own species is not modern nor progressive. It is more a testament to the harsh and brutishness of our past and not anything to be proud of. Yet too many of our American society still see racism as something they deserve to assimilate. This is one of the worst of our societal ailments and until we can face the truth of all of our equalness we won't see it's abolition any time soon.
However as we grow closer together as a melting pot within our American society the lines will cross and the color line will be much more blurred to act as an ongoing catalyst of hate and derision. The evil that is racism will slowly melt into the antiquity of our past and although it is happening much more slowly than we want it to be it is happening regardless of its unnecessarily slow pace. We destroy racism by coming together as a family and then those who hate for their own agendas will have a much harder time justifying it.
