Again I'm just a visitor here in this sub-forum but I think this point is important, about painting cultures or individuals from certain countries with too broad a brush.
Some generalities occur related to perspective, in regards to culture, but it's easy to slip into describing most of the people in a country, from there or foreign visitors, as all the same way, and people don't tend to work like that. If they're filtered for some reason that can hold up, as in an expat forum where people might feel an affinity to a very local group perspective there (local in the sense of being part of that group, not regional). Or from very limited area (physical region) and social class generalities can hold up better, but even then members of the same families tend to vary as people.
A second split occurred in that characterization, between narrow-minded, non-integrated expats and broad-minded, self-aware and selfless types. Oddly people do somehow tend to gravitate towards one extreme or the other, over time, to embrace cultural shift or not, but it's not quite that simple related to a good versus evil sort of spin. Or at least not in my experience. Someone could integrate fairly well and still be a despicable person or remain separate from local culture, and not well versed in it, and still be quite decent.
For me it works to balance noticing generalities that are meaningful carefully against individual differences (eg. painting Americans as being loud and culturally insensitive), and try to dig deeper related to noticing why foreigners might tend to not integrate or integrate well, to why such extremes might really occur. I don't completely disagree with the broad conclusions stated here in discussion, they just work better filled out a little, and framed to limit what the claims say to what they really mean.
