She has a very basic thinking in that whole topic. No knowledge about history, biology and even present what is happening in Asian countries and probably in her own. Just living in her own bubble which she created to remain "happy". Like fore example she is proud about Uyghur people, but she little knows that they are oppressed in China.
I imagine "mocking" others culture clothes like the first picture, that weird dude. Tell the second girl she can not wear Bohemian style, because she is not Czech. the third girl is not Russian, the fourth girl can not wear tartan, because she is not Scottish and the last is not French, all those clothes are part of someones culture and became everyday clothes. (I think all those girls rocking those styles and same as your examples they do not mock other cultures clothes)
