I realize that many Boers are too poor to emigrate and/or are too tied to the land by centuries of culture. Nevertheless, if Holland REALLY wanted to solve its Moslem problem, handing out free visas to every willing Boer would be a good start.
As for Boers in the American Southwest -- I'm aware of this too. On a hunting trip a few years ago, my friends and I were far, far out in the depths of the California desert, and lo and behold, there were a couple of small settlements with Afrikaner names. We surmised that perhaps Afrikaner mining engineers were brought in to extract the minerals or some such scenario, but we don't know for sure -- we didn't meet anyone we could ask.
BTW --regarding "stopboergenocide.com" -- more power to them. A noble ethnic group such as the Boers deserves to survive. They need to get their fertility rates up though. Have you read "Death of the West" by Pat Buchanan, regarding that subject?
Koeksister is a worse nightmare than boerewors :-) It's not for the low carb set most definately.
