Name one outrage among conservatives in the US when a white person was cast for a role that was any other ethnicity in the source material. Sure, it happens on the Left, Netflix is especially accused of white washing (recent example: Three Body Problem). But, conservatives don't give a shit when it happens the other way around.
Regardless, I truly couldn't give a shit who gets cast for what regardless of source material. If the actor/actress is able to play the part well, I come for entertainment and couldn't care less.
