Tokenism isn't the way to go, equality shouldn't mean that there should be the exact same number of white people as black people as asian people. It shouldn't mean a black actor gets nominated just because he's black and they're trying to show they can be diverse, when the reality is a white actor deserved it more, that's just an insult. Equality should mean that everyone has the same chance to be a member/to win an award. There are more white people in America than black people, so it makes sense there's more white people in the Academy.
People point the finger at the Academy for lack of black nominations (they aren't perfect either) but I think the problem lies in the industry in actually creating opportunities for more ethnic people to work in the film industry. However, again on the other hand, studios are business companies, and they make movies to make money and the audience doesn't react to films with black, asian or women leads than we do with white leads. That's just a fact. Look at Ghostbusters, look at a number of films. If doing films like that are going to lose them money because of those choices they aren't going to do it and that's down to us. I don't think 99% of Hollywood has any agenda against minorities, they just listen to the box office receipts and what we the audience tell them through that.
