"The "concentration camps" thing is a popular US urban legend"

I'm not American, nor do I live in America, therefore I am not exposed to American Urban Mythology.

The British interned Boer families: men, women and children in concentration camps during the boer war. These were the first concentration camps, existing purely to "concentrate" boers in one place.

They weren't prisoners of war or criminals.

Hence the terms used.

PS I am also neither Boer nor Dutch.

The boers descendents, Afrikaaners, remember the cruelty of the British well (Ironic given their treatment of Black and coloured Africans yes, but true nonetheless).
