it's a copypasta/bot and it's here every single day. the 'we're all going to become one uniform race with a monoculture' angle does raise my blood pressure abit due to how incorrect it is though, there's no chance that 8b people and growing will ever mix into one uniform race over time. it doesn't even happen in places where multiple ethnic minorities have existed since time immemorial like the middle east. you can plot their ethnic groups on a map.
