So What's the Deal?

They tell us race is an invention, that there is more genetic variation between two black people than there is between a black person and a white person. Then they tell us black people have a worse kind of everything-from Poverty to Covid-19. The worst kind of breast cancer and get more fibroids. And white dudes get cystic fibrosis and osteoporosis. So what's the deal, Present or future doctors in the house? Is race an invention or not? If it isn't then what is it???
