as someone whose culture is often appropriated by silly Americans (mostly, there are others but the majority are from the US) claiming heritage that they likely don't actually have, its funny more than anything else. The thing that annoys me most is people commercialising Scottishness and making it all about clan tartans on shortbread tins; but its Scots folk doing that so its not really "appropriation" and the only way of really solving that would be ending capitalism, which would be a fun thing to try.
Its probably one of those political positions that's hard to put on the spectrum; people on the nationalist far-right don't like people from other places "stealing" their culture as well.
I mean, the main trouble with it, is it that the phrase should have a "mis-" prefix before "appropriation". That would clarify some of the dumber aspects of the whole malarkey.
no that's far too sensible, the only solution is to create one big world culture that everyone follows since diversity is a bad thing
But yeah there are right and wrong things to do these things and its all about respecting whatever culture you're dealing with, which is the decent thing to do anyway.
