Unfortunately I think most of the damage has been done. Populations & cultures are mixed. There is no way to undo the situation in most places without some further sort of theft or injustice. And beyond that, 70% of the population got gene editing covid injections.
There is no "right" of collectives to maintain anything, only individuals have rights. Individuals have the right to choose mates who look like them if that is something that concerns them. Individuals can voluntarily build communities & private institutions focused on race & culture if they want. But I would recommend focusing more on cultural alignment than racial features.
The world's primary proplem right now is a number of inbred families who have become literal blood sucking pedophile monsters as a result of their obsession with eugenics & their desire for control over others.
