Racism is an invented liberal term.
The only thing that exists is being aware of differences in the characteristics of people of a given race.
When it is said that Germanic people are better engineers because of the high concentration they can put into small details, it is not much different from saying that people of West African descent are better sprinters because of the high density of fast twitch muscle fibers they possess.
These differences are clear and are TRUE.
I believe that racism or discrimination in general, is a primitive fear of what is different. From a genetic and evolutionary point of view, we value for example, facial symmetry, because we take it unconsciously as a sign of health and therefore healthy genes, the same can be applied with race, certain physical traits or aspects (neoteny etc) of culture that we take as positive or good because they are familiar to us and because they have the approval of the group (whites), the latter is also very important, we are social animals, although nowadays it is easier to survive alone, in the past the individual who was alone was practically condemned to die, while belonging to a group guaranteed food, protection, reproduction, in short, survival: survival. That is why I believe that feelings such as compassion and attitudes such as tolerance are signs of evolution, as we overcome our primordial fears, in pursuit of having a society that, in the end, if it works, benefits us all.
in the west clearly being Caucasian or having white features gives you privileges as the whole culture is centered on it.
racism exists everywhere on earth but evolutionarily I have no explanation as to why it happens and why we generally prefer Caucasian or light-skinned features etc.
