I’m curious as to where this anger about “appropriation of culture” comes from. It sounds like it’s a financial thing ang that natives are pissed off when other people make money doing fake versions of things they invented.
As far as I’m concerned, cultural appropriation happens all the time, and it’s a good thing. It is through the intermixing of various traditions that we can learn to appreciate each other.
As to the criticism about doing things the wrong way—again, borrowing from other cultures happens all the time, and no one culture “owns” their own culture. If it’s in the public domain, then anyone can use it. You can’t take people’s experiences away from them unless you perform a lobotomy and people will make of their experiences what they will. There are no rights to culture. It’s free for the borrowing.
Now anyone can say that this version or that version is not authentic, and that’s fine. People get what they want though. Some may want “authentic” experiences, and others may be fine with a sweat run by someone who knew someone who did a sweat with a native sometime.
You can rail about these practices, and try to persuade folks that it is worthless to experience them, when the real thing is available free (which, of course, it isn’t, since it costs a lot in terms of money and time to locate someone who can “legitimately” perform these rituals).
Culture can not be exploited. It’s not like property. It’s not like anything. It’s just abstract, and it is different to everybody. Many cultures invent the same thing as other cultures. Are they stealing, or doing something that is appropriate for their own culture?
Can we compare spiritualities? Is one spirituality better than another? More helpful? This kind of thinking is nonsense. You can argue it, but you have no way to prove it. Each person will experience for themselves, and have a preference, but that doesn’t mean the preferred spirituality is better for all people.
I’ve drummed for a sweat and then participated in one. The more memorable experience was keeping a hearbeat rythym going for an hour or two. I’ve heard native American flute and drumming, and I’ve incorporated ideas I’ve heard there into my own music. I’m not pretending to be any kind of native. I’m just pulling together what makes sense to me.
If it is the pretending of authenticity that is a problem, that happens all the time. How many people might copy words on fluther and pass them off as their own? We try to protect intellectual property with copyrights and such, but so many people still don’t attribute properly. All I can say is that if you model the behavior, then others might follow, but if you whine or demand a behavior, you’ll be spitting at a volcano to put it out.
