This is a necro'd thread from last year. One thing that did occur to me (before I noticed the date) is that everyone seems to be thinking "Concentration Camp" = "Nazi".
There have been plenty of concentration camps by plenty of different groups throughout history.
It wasn't just the Nazis. The Nazis have kind of ruined the word .. before that (say World War I) people had no trouble calling centralised camps to contain foreigners as 'concentration camps'. (Because they concentrated the groups into one place for administrative reasons)
eg - If you a Lutheran in Australia during World War I you might have ended up in this concentration camp:

So remember - concentration camps weren't just used by the Nazis ....
