Cultural appropriation can be a sensitive topic. Who has the right to say what is and isn't cultural appropriation? It's not merely confined to someone wearing a headdress. When someone uses what they think is "Native American themed" or "inspired", it's likely appropriating cultures that are still alive today. It can be telling everyone that your great great grandmother is Cherokee without proof.
Cultural appropriation is harmful. It promotes and perpetuates stereotypes and seeps into every aspect of Native lives. Hard to believe, but it's true. It may not affect the average non-Native, but too many people are guilty of it for it to continue today.
