Imagine now a USA without white people? Would it all be peace and love? No. Blacks would fight with Latinos and asians and try to lay the “White Guilt” on them—but they will not accept it. Imagine if all the Latinos, asians, and Native Americans were gone from the USA. How long would it be before the USA became a stink pot African “Republic” of a few very rich blacks and a whole lot of starving blacks. It would rival, in my opinion, Haiti.
Or imagine if we were not the majority or descended mostly from North European stock. It’s easy, actually, and involves a quick flight to any country in South or Central America. Or go to Africa and see how their societies (dis)function.
