Jabberwok From the link I posted
When concentration camps were built in South Africa, for white Boers, he said they produced “the minimum of suffering”. The death toll was almost 28,000, and when at least 115,000 black Africans were likewise swept into British camps, where 14,000 died, he wrote only of his “irritation that Kaffirs should be allowed to fire on white men”. Later, he boasted of his experiences there: “That was before war degenerated. It was great fun galloping about.”
Whatever his role he certainly didn't oppose concentration camps.
almostelderly read what he said about people of other races and skin colour and then ask yourself how you would feel about him. He has a history of oppression.
And to those who are telling me it was because of the time he was born in. There were internationalists then who knew it was wrong to oppress people.
