Races are not considered to exist in a biological sense, only in a sociological sense.
There may be vast differences throughout humanity, but these differences can not be easily grouped together into easily distinguished “groups”.
humans came up with the concept of “race” based entirely off superficial traits like skin, hair, facial features, etc, long before we had an understanding of the human genome. While it may seem that people in, say, Saharan Africa have been “isolated” from people from other parts of the world, in a genetic, evolutionary sense, they really haven’t been, so they can’t even be classified as a different “subspecies” or “race’” or what-have-you.
the fact that people are like “Coca Cola supports racial equality, I’m not going to be drinking Coca Cola anymore” and “Google supports gay rights I’m not going to use them anymore” like what next “the Earth provides Oxygen to ethnic minorities I’m going to stop breathing in protest”
or maybe “the band i ‘like’ did something that isn’t exactly in line w my values so i can’t listen to them anymore.”
