another example: how many times are immigrants criticized for wearing clothing from their native land, for not assimilating/blending in...but let the 'right' designer or celebrity appropriate said clothing, it's suddenly acceptable/fashionable....
I have to agree- that double standard isn't right- shaming somebody of Indian/Chinese/Korean/other descent for wearing their ethnic dress just sucks.
When I see Indian women wearing Sari, I don't think "exotic" or "foreign", I just think "Cool!" Likewise the clothes of other cultures. I feel that if somebody wants to wear their ethnic clothing, they should absolutely feel free to do so without being shamed, whether they're showing ethnic pride, doing it just for comfort, or whatever.
And yes, I get a bit annoyed at the "PC police"- that is, other (usually) white people who take it upon themselves to be the arbiters of what's appropriation, and feel entitled to be incredibly self righteous with anyone who disagrees. Especially when they persist in this stance, even over the wishes of people from the culture that they're "standing up for", when those people say "I'm not offended if somebody wears my outfit/learns to play my music/eats my food/practices my dance or martial art"
