What a fantastic piece, Aimée!
I too get so damn bored with the same white people and the same old stereotypes. It's actually a big reason I mostly read books by minorities now.
If you want to chase this rabbit a little further, I highly recommend Bad Feminist by Roxanne Gay. She address this issue in a number of popular shows that are whitewashed in this way. (Assuming you haven't read it already!)
Thanks again so much!!
