Remember Argentina used to be 85% white and the rest light-skinned mestizos
Many years ago, Europeans stopped coming and immigrants from Latin American countries began to come,mainly people from Paraguay and Bolivia.
Now the native population is being replaced by brown people
In Argentina all this is completely ignored
the kids are brainwashed by telling them that the argentinian is the mestizo
some people even deny that the country was ever white

Much of Patagonia was settled by Welsh immigrants. They aren't white either.
