Thank you for this! I've been trying to voice these same opinions, but it always comes out sounding horrible.

I totally agree that Hermione was written as white. This retroactive representation is incredibly annoying. Just the same as Dumbledore suddenly being gay was annoying. If she had wanted the character to be black, then she would have made it clear. It's an incredibly easy thing for her to say to the contracted artist for the books "she's the wrong race." Same with the movies. You don't get brownie points for allowing others to represent other races in your work.

And this all seems highly suspicious to me coming a few weeks after "Fantastic Beasts" got slammed for lacking diversity. It seems more a "I'm not racist, here's the proof" ploy than anything else.
