> thoroughly race mixed within 500 years  lol.  southeastern and southern brazil only had racial mixing in the early colonization, just like afrikaneers. after that, there was a thoroughly mass immigration from portugal until like the 1910, so whites married whites, kind of similar to what happened in south africa, but without an official ban.  the mass racial mixing happened once slaves were freed and the empire believed in the 'whitening of blood' policy through miscigenation. after that, it only went downhill with the republic trying to create a "sense of homogeneity" encouraging racial mixing.  i assume it is the same for argentina and uruguay as well. so basically, the mass miscigenation is only 160 or less years old. it shows how much can be destroyed in less than two centuries.
