the Problem of UU Cultural Misappropriation.

One of the big UU bloging topics this week is cultural misappropriation, and more exactly the use of that term in the upcoming revision of the UU “Principles and Purposes”.
The idea is one of those things that sounds good on the surface, but may not be. Because where will the line be drawn and who draws it?
Let me give an example from the other week. Person A was talking about a Native American cultural item that they were using that just wasnt what it used to be.... Person B jumped in all upset about cultural misappropriation of the item and chewed the Person A out. The major problem was that the item was given to Person A by a close family member, who was Native American. Is this cultural misappropriation or not?
This issue was brought up first by Rev James Ford - who questioned if the entire UU Buddhist community might be alleged by some to be guilty of cultural misappropriation. I've been to a Passover Seder, invited by a giyoret. Am I guilty of cultural misappropriation for accepting the invitation? In the UU hymnal, we have changed wordings from the original of certain songs - aren't all of those hymns cultural misappropriation? Since many of our Congregations are not Christian, can we sing Christian hymns without it being cultural misappropiation? One worried blogger even wondered if this whole thing was an attempt to force the UUA back to its old vision of Unitarian and Universalist Christians. - because that is the UUA's heritage.
The other worry with this whole thing, is that like most of the rest of the proposed P&P, it's full of legalize and academic speak. While the whole thing might be to force UUs not to treat it as a creed, what if they do? Do we want to affirm our Anti-Cultural Misappropriation every Sunday (assuming we could still meet on Sunday that is )?
Rev Ford nicely suggest a change of wordage to what is essentially "be sensitive". This is something that I could affirm, something that sends a positive message rather than a negative message. As for the whole idea of cultural misappropriation: we can simply remember that "if you dont know what you're talking about: dont ."
