I don't really care what country. I do think this attitude is more widespread amongst Americans, having lived here for a while both as a minority and as someone who lived outside the country, and it's really easy to see this kind of attitude from people here. Admittedly, they may be from some other country. I don't really care.
But maybe pick a better fight than 'ohno she picked on America' instead of using ad hominem because you can't attack my points.
