I get that it gets blurry. But not every time a minority is hired to play a traditionally white role, is it a diversity hire. It seems the conversation goes like this.
People: You should hire whoever is best for the job, without considering race or whatever.
Studio: Okay, we think this person is best for the job
-points to black or Asian actor-
People: GOD DAMN DIVERSITY HIRE!!
I won't defend the 7 dwarves thing, cause who knows? But why on earth couldn't they have thought Halle Bailey was the best choice for the role? There's a very unsettling double standard to demand they not consider race but then accuse them of it when the person isn't white.
Again, taking the 7 dwarves out of this because I have no idea what they're going for there, unless we have some strong evidence that it WAS just a diversity hire, then always accusing studios of that is rather distasteful.
