I don't often speak on topics like these because I always feel like I'm probably wrong or not educated enough, but I guess I'll take a shot. What she is doing seems hypocritical to me. Not something g worthy of her being attacked by everyone on the internet, but something that definitely warrants a "I did do that, and I didn't realize how it could bother another culture in the same way having to do an Asian accent bothers me. I know better now, and I'll do better."
As far as appropriation in general, I feel a few different ways about it. If it's used mockingly, then there's no question, it's fucked. If it's done for the purposes of stealing roles and seeking financial gain, its fucked. BUT, if you're a kid who spends all of their time with people of another culture and you adopt an accent or some other aspect of their culture…..I don't have an issue with it. It happens, and it's natural. People I know that moved down to Georgia come to visit with the thickest accent, and they don't even know it happened.
I know this is touchy and I know this is where I may be wrong, but I'm definitely open to learning. I've just seen so many kids growing up who were picked on terribly and found their only friends in groups from other cultures. Over time they would appropriate certain aspects of that culture. If they were attacked the way I see some people attacked, I honestly feel like they would have committed suicide. This is what makes me divided.
Again, if anything I'm saying is wrong, I apologize as I have no intention of offending anyone. I'm learning every day, and I'm the farthest thing from perfect.
