No. It’s not. That’s merely the sociological tool as a gateway to muddying the ethnicities to negate the existence of white people.
Another way is the lie that white people don’t have melanin. Only albinos don’t. There are TWO types of melanin and each is produced by different genes. Eumelanin, which has been around longer in humans, is responsible for black and brown colorations.
People who evolved in northern climates lost the entire gene for Eumelanin, and evolved another gene that creates pheomelanin, the second type of melanin. Pheomelanin is responsible for yellow and red colorations. The loss of the Eumelanin gene and the evolving if the phenomenon gene occurred about 30000 years ago as a response to reduced sunlight in northern areas. For most of human history since that loss, humans only had one or the other. In more recent times as people traveled and mingled, someone can have both.
The genetic ‘white’ is thus scientific. White people gave pheomelanin, not ‘no melanin’
The modern definition of ‘white’ that they have pushed to undermine white existence, is merely a sociological one.
Side note— a super saturation of Eumelanin gives you a very dark individual with black hair and dark brown eyes. While a super saturation of pheomelanin gives you a ‘ginger’.
