Notwithstanding your New Year’s rant pikey, I suspect that Pete makes a good point. In reality, the winner(s) of a conflict are usually the ones whose view get recorded in history as the so-called ‘truth’.
Generally, they are able to minimise (or even airbrush out) any of their shortcomings and maintain focus on their righteousness etc. Nobody pays much, if any, attention to the loser’s point of view.
That said, I think that your drawing the distinction between “concentration camps” and “extermination camps” is excellent if only because it highlights the principal purpose of the ‘camp’ rather than the fact of its existence.
However, the main thrust of my argument still stands. All this constant harping back to what the Nasis did or didn’t do is so last Century. Time to move on eh?
