That idea that embracing your “Native American roots” by either wearing a fake indian headdress or stereotypical and often ignorant facial paint - says more about your “native roots”, meaning you don’t have any!
Hi my great grandmother was half Cherokee and I’m pretty sure she wouldn’t mind people wearing what they want. You shouldn’t have to justify your dress with ethnicity. Why is race still even an issue >_
Your great grandmother would be okay with people promoting racism against Native Americans? I’m sorry your great granny was a racist; I hope you can learn from her mistakes.
