Moreover the quoted paragraph does support that claim, and you still have not engaged with it. You are the one failing to understanding statistics. The quoted paragraph does not support the idea that people can’t be categorized into races, of course depending on how you define race, but you’re the only one talking about that.
I think you need to check your tone and stop trying to politicize this discussion. You might have good points, but I’m really disappointed in how you seem to be trying to incite people.
