Personally I can care less of where an individual or a group of people are from, though it doesn’t discount the fact some generally come off as very rude and are very different, though in their own national setting is acceptable. My wife is very bigoted, she is very outspoken about her dislike for Chinese, Hindi’s, Muslim of any nationality, Germans and Cambodians, a non human sub-species in her view. She doesn’t have any hatred toward Burmese, she views them as a lower level of human yet she’ll converse with them and smile. When I preach to her that all humans are equal and fallible, she looks at me like I’m from a different universe.
