Oh my. I feel like the sell-by date for stuff like this was the 70s. At the latest.
I know at storytelling/spoken word people will tell stories from other cultures -- sometimes quite well -- but. But but but. They don't dress up, and they do their research. And they would immediately step down if anyone said, "hey, that's from my culture" -- because I've seen that happen, and it's always been a gracious, sharing moment.
This, on the other hand, is... I can't even.
