That’s your argument? Race exists because it’s helpful to professionals? You seem to misunderstand me. Race as a concept, useful or otherwise, exists. Biological differences between ethnic groups profound enough to warrant the distinction as a separate type of human do not.
You believe that ‘white’ which includes hundreds of random groups of Europeans and Asians (and others from all over the world), and whose only requirement is appearing to have white skin, is a distinct physical group from ‘black’, which also includes hundreds of ethnic groups from all over the world; these are distinct biological categories?
I can show you a textbook that says God made the planet 5000 years ago, or that blacks are by nature rapists. So, yeah, you need to read more about this from people who know what they are talking about. You also ignored my questions about Communism, btw.
