Sure, I don't think there are many who would disagree that tokenism is crap. But quite often criticism is why is there minorities at all, for example - why is Tracer a lesbian, why is a minor transexual character in dai. Not that they are poorly written or don't fit in game world. Just that they exist. If the thought is "I don't want poorly written characters whose only character trait is that they are minority and they don't fit in story or context". I agree. I don't want characters like that either. BUT well written inclusive characters do make the game better.
Well written characters make the games better wether they are minorities or not. One major complaint is to write a character just to state from nowhere "oh he is a drag queen btw" when that never had any part in the story.
