It's because of a painful history, some distant and some not so distant. So it is in people's minds pretty often. Other places have this as well. In Western Europe it is perhaps ww2 stuff. Someone here just yesterday claimed they don't want to use the 'ss' Linux command to diagnose socket issues because of how it relates to 'ww2'. In other parts it is all about nationality, if you call someone by a different nationality, they might be terribly offended by it. It looks silly from the outside, but once you live there it makes sense why there is emphasis on certain things like that. I think you have to grow up in a place to internalize that. When I was in Portland with a co-worker, who was born and raised in US. He leaned over and whispered "Have you noticed, how everyone is white here?. It's freaking me out". But I haven't noticed until he mentioned it. For better or for worse, it is just not something I think about. But he did.
