The idea that nobody cares about race/sex seems very indicative of privilege. White males not understanding why people get so bent out of shape (again not assuming that @wynnduffy is a white male) about skin colour of characters is precisely because they don't and never have felt under-represented in media and don't need any extra empowerment.
Why do you think a person's desire for feeling represented should be satiated because they can shoot other players as a character who shares their race and gender?
Why do you get to decide whether or not people can enjoy being represented in games? Is there some fault in being a person of colour or a woman and wanting to play games or hear stories about people like yourself?
It's easy to say representation is trivial because there has literally never been a point in the life of a white male where they couldn't walk in to a game store or movie store and pull several hundred titles off the shelf about people that look and talk like they do. If I lived in a society where I very rarely and infrequently saw stories being told about people like me then I'd be pretty happy to participate in or consume one when it comes along.
