Racism

Racism is a belief that humans differ in heritable traits making certain groups superior or inferior to other. The true is that neither the color of your skin, hair and eyes nor the shape of your head is determining your character, intelligence or skills. The genes responsible for that are independent from each others. Many differences in appearance are effect of adapting to very different environmental conditions. One of them is production of higher amount of melatonin in organism exposed on stronger sun radiation causing darker skin shade.
Precursors of racism were white people who started discovering and conqesting new lands and continents. Looking for cheap workers they were kidnapping native Africans to Europe or USA making them their slaves. They looked different, had different beliefs so they were considered to be worse.

The real roots of racism armed conflicts, discrimination, sexism and intolerants lie in unemployment and disintegration of society. I don’t understand racism. Judging people basing on external features or cultural differences makes no sense to me. These kinds of prejudices are very primitive.
