Basically?
White Liberals: "We know best. Worship us as your defenders and saviors!"
Anyone Sane, including Native Americans: "Fucking weirdos."
Ha! I remember one funny incident back in college, when I still lurked on FB or Meta or whatever it's called these days. Basically, some girls posted pictures of herself in a kimono while in various poses. Cue the righteous lectures on cultural appropriation and other BS, only for the girl to post a photo of her
Japanese passport with the details blurred out the next day, along with messages of support from Japanese members of the site.
For once, the self-proclaimed moral guardians actually used their brains and just dropped the issue.
EDIT: I mean, cultural appropriation is BS when you think about it. Logically, condemning and stamping out cultural appropriation would end in mass ethnic cleansing in the USA alone, with all non-Native Americans having to be banned from speaking English before being deported back to Asia, Europe, and Africa.
EDIT: Actually, now that I think about it, in Asia you are
expected to appropriate their culture, especially if you intend to stay long. Historically, one reason Westerners were looked down on in Asia was their refusal to learn to speak the native languages, or to adopt the local fashions. In fact, AFAIK, many Japanese today will 'politely' ignore anyone who doesn't speak/can't read Japanese in their own country, or encourage foreigners to wear local clothes (kimonos or yukatas for example) while attending local celebrations. Foreigners that do speak/read Japanese, and respect local traditions, actually get treated very well, almost as though they're Japanese themselves.
