first of all, south Asian people are not a monolith. we don’t all have the same opinions and viewpoints. and we certainly don’t need you, spacexualkids, a known mayo white girl, constantly speaking over us about race issues. that’s the opposite of being a good ally.
personally I didn’t find Lexa’s headpiece offensive. I’m Indian and grew up wearing bindis pretty regularly, mostly on special occasions. while watching “the 100” I didn’t even register the headpiece as a “bindi.” I never found it offensive.
I’ve heard someone theorize that the headpiece was supposed to resemble the “helm of awe” from Scandinavian history, which to me makes more sense in-context. But I recognize that some desi people within the fandom did find the headpiece offensive, and they have every right to feel that way.
But again, I don’t think it’s your place to get on your soapbox and speak out about these issues, seeing as you’re not desi yourself.
Listen and amplify the voices of actual desi girls (even those who disagree with you), before spreading your own ideas and making sweeping generalizations like this.
