The fallacy of white supremicy.
There are three ways of determining truth. One is pure thinking, two is observation or experience and the third is science. However, science is the method for certifying everything.
Science is simply knowledge of the world that has been verified, that is, proven to be true rather then repeated as a rumor. You cannot sit down for breakfast without science. When you sit in a chair you are doing a scientific experiment. You are testing an assumption that the chair is strong enough to hold you.
Many problems, including white supremisy violence is based on skin color and the assumptions that accompany it. This is extremely tragic since sciencce has shown that there is no relation to anything else in a human other than the exposure to sunlight.

1. We are all Africians. Between 50 and 100 thousand years ago, groups from a number of tribes in Africa began an emigration illuistrted in the map below. This is determined by evaluation geneomes taken from cheek swabs of present day humans. There is no significant difference based on skin color expect those genes that control the creation of the pigment melenin.
All our ancestors were various shades of brown becuse of the pigments in their skin that protected them from the African sun. As they migrated north, the need for vitamin D required that the pigments in their skin lighten or be eliminated.
The map is from National Geographic Magazine.
Because of the importance of the issue of skin color and the false conclusion of white supremicy, I include an extended quote from Wikipedia.
"There is a direct correlation between the geographic distribution of ultraviolet radiation (UVR) and the distribution of indigenous skin pigmentation around the world. Areas that receive higher amounts of UVR, generally located closer to the equator, tend to have darker-skinned populations. Areas that are far from the tropics and closer to the poles have lower intensity of UVR, which is reflected in lighter-skinned populations. Researchers suggest that human populations over the past 50,000 years have changed from dark-skinned to light-skinned and vice versa as they migrated to different UV zones, and that such major changes in pigmentation may have happened in as little as 100 generations (≈2,500 years) through selective sweeps. Natural skin color can also darken as a result of tanning due to exposure to sunlight. The leading theory is that skin color adapts to intense sunlight irradiation to provide partial protection against the ultraviolet fraction that produces damage and thus mutations in the DNA of the skin cells. In addition, it has been observed that adult human females on average are significantly lighter in skin pigmentation than males. Females need more calcium during pregnancy and lactation. The body synthesizes vitamin D from sunlight, which helps it absorb calcium. Females evolved to have lighter skin so their bodies absorb more calcium.
The social significance of differences in skin color has varied across cultures and over time, as demonstrated with regard to social status and discrimination.
