I've got one last post to make re: cultural appropriation and why the headdress is a bad choice then I'll bow out and if anyone wants more clarification feel free to PM me.
To maybe explain what cultural appropriation is and why it sucks here's a comparison. Let's say a kid in the middle of China hears about this really cool thing the US does, a flag burning ceremony to retire their flag! Super cool! So they go out and order a brand new US flag, dunk it in gasoline, and toss it on a campfire. Wow, it flamed up really huge! No wonder this is something the US does, that's so cool!
Of course anyone who knows ANYTHING about the actual US flag burning ceremony would be horrified, you only do this with flags at the end of their life and you cut it into strips and burn them one stripe at a time and there's no gasoline. It's to honor the flag not to see something burn, this kid missed the entire point.
Now this kid in China didn't know this either through lack of research/talking to people from the culture or being young and not knowing any better, but it doesn't make it not pretty offensive to the actual culture it affects. This Chinese kid isn't a terrible awful person, they're just ignorant, however if someone tells them they're doing it wrong and what they're doing is actually pretty terrible and disrespectful to Americans they shouldn't respond with 'WELL IT'S NO BIG DEAL IT'S JUST A PIECE OF CLOTH IT'S NOT LIKE IT EVEN HURTS ANYONE QUIT THROWING A TANTRUM'.
But that is basically what's happening.
