When is cultural appropriation OK? Never, say some Native Americans
The Indian Arts and Crafts Act of 1990 makes it illegal to knowingly sell non-Native made goods as authentic Native American art or craft. More than 600 fraud cases have been filed since the law's enactment.
But the IACA doesn't apply to the more widespread practice of borrowing and adapting Native imagery, themes, or traditional cultural expression on a range of commercial products.
