Melanine non melatonine. The color of the skin is just a fixation of those that has been indoctrinated about this issue. I never spoke about white and blacks. Russians are as different as south Americans. The physical traits anyway are just the exterior changes of having been exposed to a specific environment for hundred of thousands years. As nature selected some skin tones and facial feature so it selected behaviour and attitude. While we developed the necessity of packing together for survival in an harsh environment so others have been selected on their ability to be selfish or violent or antisocial. Unfortunately our strength, the ability to create societies and not tribes is a weakness when we are mixed with violent selfish thugs. So, they can go live wherever they like with their like-minded people and we should stay in our community trusting societies. Just as easy. And crime rates and brutality are just the evidence of what I just said. I would add...we would have already hanged most of those billioners and politicians that infest our world but the melanines dudes can't help but protecting them in exchange of some free bucks. They are empowering the worst criminals and this is why you have been made believing in multiethnic and multiracial societies... they need that.
