And no matter how carefully you screen the first blacks allowed in, their children and grandchildren will regress to the mean and invariably cause the same problems other blacks cause elsewhere.

Every White country stupid enough to allow significant migration of non-Whites in thought ''we are good people, we're going to do this right, we don't have the same history as the USA with opreshun'' aaaand the kids and grandkids comit a massive amount of violent crimes, thievery and rapes.

They got more opportunities than the natives of the same starting social status did, yet they devolve into this.

No ''not all'', but enough to gradually degrade your society into a low-trust, unstable, violent shithole like South Africa.

Demographics is destiny.

Make more of the people who produce good outcomes, or degenerate into whatever the dumbest and most fertile curretly breeds.
