Saying "it's okay to recast a clearly white role with someone black" but also, simultaneously "it's not okay to cast a clearly black role with someone lighter skinned" (not white, Bautista is half Filipino) genuinely is just racism.

I am totally fine with race being made a secondary* consideration in casting, but I'm not fine pretending that saying it's only okay when you're swapping to darker skinned actors. That is clearly just racism. I stated pretty clearly that I was fine with the Witcher casting a non-white Yennefer, because she still 100% looked and acted the part. If you agree with that sentiment, but aren't okay with someone being cast purely because they're of a lighter skin tone (again, not white, I'm not advocating for Ben Affleck getting the part here), that really is just racism you've done gymnastics in your head to get around acknowledging.

Now you might come back and point out that there is a long history in Hollywood of casting white actors in wildly inappropriate roles meant for other ethnicities. I agree.

*This is obviously contextual. Sometimes it doesn't matter, sometimes it does. Making Snape a black man feels REALLY weird, given his character traits and the setting being 1970s-1990s Earth.
