Sounds really interesting - were you working there?
Anti-Americanism is rife everywhere and I find it odd when I defend certain aspects of America to people when I go abroad because I used to be fairly anti-American myself...all good PS material I say!
Yeah, I've been working here in a few different capacities (English teacher in France, computer programmer in Switzerland). There's definitely a strong dose of anti-americanism, but more than that, there's a lot of really virulent anti-globalism/anti-capitalism/anti-technology that comes from people who don't see the irony of carrying a mobile phone, i-pod, and being employed by a website design company all the while ranting against, "the system." It's like they're totally unable to connect the lifestyles they enjoy with any of this malevolent system they imagine needs to be fought.
I think that for them America represents the heart of "the system," and so their anti-americanism is an outgrowth of their general beliefs.
