One off the things that pisses me off about the idea of cultural appropriation is it often means people feel like any complaint about people using symbols etc is just the same stupid shit, and should be ignored
Going right back to the 1980's ( in Britain,) Native American culture was becoming a 'thing' in alternative circles....I used to go to camps......when lots of people would live in a tee-pee, sing songs about White Buffalo Woman, wear hand made moccasin and so on....they took it very seriously...as it was seen to be a way of reconnecting with the earth, and a spiritual path. The use of 'Medicine cards' and having totem animals, making your own dream catcher.
These days you see shop bought dreamcatchers hanging from car rear view mirrors, and lots of people have them without having any deep understanding of the culture behind them.
The American airforce named its missiles Tomahawks and flew in Apache helicopters.......I could see more offence in this...even though I imagine they were adopted as names because Native Americans were also warriors and had developed an array of fearsome weaponry.
Remember Madonna's video for Like A Prayer?. That caused some consternation and upset at the time.....but i do think that there seems to be more tolerance of such flagrant challenge, and also appropriation of religious iconography in much of 'the west'. I guess that kind of tolerance comes in cultures in which degrees of personal & moral relativity are considered normal.
As for canoes, kayaks, sarongs, crosses, bindis, plaits ( even cornrow ones), decorative dreamcatchers, tartan bags and scarves and any other number of decorative or even iconic images from any number of communities........after a while getting precious and irate serves little meaningful purpose other than to nurse and nurture wounds & grievances.
