Is that your advice to Americans if things go that way here? Where do you expect all these people to just get up and go to? Name one country that elevates those of European ancestry above others, even in Europe.
America will never be 85% Black. If I was living in an area that started becoming heavily black, I would leave. See Philly for blacks destroying a formerly decent city. (I was born in Philly and lived outside of it for 15 years) Many of the whites in S.A. won’t leave, but I certainly would. I would try Australia, Canada, US, or a northern European country.
