I've been there, absolute last thing I could think of is smiling for a big happy photo. One of the gloomiest places I've ever been, and for a couple days after it just had me thinking about how evil people can be and just 'why?'.
That said, I think this is a typical self appeasing over reaction. She went there, she's showing an interest, which is more than can be said for probably 2/3rd of Americans. I mean like that article is a perfect example. Oh you're so offended at the disrespect she showed? Towards this sacred place which you are so involved with that you don't even know what country it's in? I can remember when I first learned it was in Poland and being surprised (because like others I too assumed Germany) but I was like 11. The reporter is showing a child like knowledge of geography/history, yet at the same time she's chiding someone for a childlike self-centered mentality? Honestly the worst I could say of her is that she's immature and not appreciating the magnitude of such a place. But again, I'm sure most forum posters here (like dreambig said) have done some incredibly stupid shit, which if viewed from an outside perspective without the benefit of context or knowing you were wasted, would look just as bad or worse, we were all just fortunate enough not to have to get scrutinized on the internet by PC heros.
People love to get offended these days. In my mind it's truly a modern day which hunt, and a means to appease your own guilt. If I call that guy who said 'black' instead of 'African American' a racist, then that means I'm clearly not racist, and I can be excused if I cross the road when I see two black guys coming towards me.
Same thing here. If I get outraged over this girl who showed disrespect at Auschwitz, then clearly I'm a friend of the Jews, and can be forgiven for not taking a slight interest in history, even knowing the name Berkanau, or knowing what fucking country it's in.
