I'm just wondering if anyone spoke up when Memoirs of a Geisha was cast with three major Japanese characters being played by Chinese actresses, or when Thor was cast with a fairly major Nordic character being played by a black actor.

All the above mentioned actor/actresses did a great job in their roles. I'm not saying anyone didn't. I'm also not saying that it's ok to change the races of characters by using actors/actresses that are from entirely different races. I just want to be sure that if we're going to cry havoc and let slip the dogs of war, that all culprits are equally tarred. We shouldn't pick and choose who gets defended and who gets pilloried if everyone is committing the same crime.
