Yeah, it's not a quota. But diversity is still a qualifier that they use to choose their actors. And that's the thing that detractors have a problem with - but considering how cynical and money-oriented the movie business is, it's disingenuous to say that this particular qualifier is the bad one, especially because this particular qualifier is possibly the only good intent the film you are watching has. Everything else wants your money. Is it so bad that this one little thing just wants you to think of non-white people as, you know, present? I don't think so.

That said, and though I love Idris Elba, I don't want him to be the next James Bond, nor do I want an Asian woman to be James Bond. To me that character is a white British person, or some white person who can fake a British accent. Maybe hypocritical, not sure. Just a feeling. And also I'd find it ridiculous if Thor was black or anything but Nordic. Prob other characters as well. But that's my headcannon of these characters. Prob in decades to come people will pfft at my opinions here because they don't make sense. But they exist.
