No one can figure out what level of diversity is acceptable.
I mean, take overwatch. You've got people angry at its ''''unrealistically'''' non-white cast (generally these being the ones you can safely ignore), but then there are people who couldn't care less, people who like it, people who like it so much that it validates the game for them, people who like the diversity to such an extent that a recent costume giving a poc chalk white (not caucasian) skin feels like a betrayal, people who feel that there needs to be gay representation despite no characters having any confirmed sexualities gay or otherwise, and people who see the game as just another example of the terrible state of diversity in video games.
A correct level of diversity does not and will never exist. It's a very personal thing to each person, which is why arguments of it tend to bring out the worst in people.
The only thing I think most people agree on is that we can do better than we're doing now.
