They do this quite a bit

'Concentration camp' remark threatens Pope's visit to Israel

I wonder if they just don't think about these things, or just don't care. The Pope himself has enough experience in a high profile position to know what he should and shouldn't say, and one would think any of the Church bigwigs speaking in public about them would too. Or perhaps they're just speaking truth to politicians and diplomats who don't take these things too well. Whichever, 'Concentration Camp' has come to mean just one thing in our culture, and that's 'death camp'. One shouldn't use it to mean anything else anymore, especially when talking to Israelis and Jewish people...
