Having gamed for three decades now I'd say the shift has been very real. There's a much larger fraction of games that have representation of women, mental illness, disabilities, races, etc.
Is that progress or destruction? Depends on which side you fall on.
You're saying there are no examples, does that mean you think no shift has happened? That games are still made the same way? If so, are you claiming that games always had this sort of diversity of representation? Or that games nowadays still don't have it?
It's similar to asking was the end of Jim Crow or slavery progress or the destruction of white spaces and to be sensitive to the people who wanted those to continue. I think a lot of the issues we have today are because people in both periods did not ostracize those people like Europe ostracized the Nazis.
Having a main character that isn't a straight white male is so minor in comparison. But giving that idea credence is a dangerous path backwards to those arguments of the past
So when people, who don't like this change, point out their dislike of it, the reasonable reaction would be to argue that the change is good. Not that there hasn't been any change.
It's really not that deep.
