Let me be clear on one thing - a politician cares about votes, they seldom put their money where their mouth is and normally try to live as far away as possible from the issues they have had a hand in causing. If you judge an entire subset of the population by the politicians claiming to represent them, you are going to end up hating millions of people, that's a given.
As far as commitment to inclusion, do you think only LGBTQ people or those from ethnic/racial minority backgrounds are supposed to be included in entertainment? What about the deaf, the blind, the physically/mentally disabled, religious minorities, aborted fetuses, pets, communists, white nationalists, national socialists, black panthers, RTwP fans etc.? How do you accommodate all those people without offending anyone, coming off as cheap or mismanaging the budget? Maybe there's a totem pole I'm unaware of.
That's just it though by your votes you are deciding how you are viewed...not the other way around. You don't like how they are representing you? Stop voting for them, it is that simple.
And yes, except for the hate groups you listed, most of those groups are represented in games where the story is broad enough to include them. It's only a few keystrokes or one artist's rendering to add a detail to a character. Obviously not the player character, but I really can't think of a single old or new RPG game that didn't have at least one physically handicapped NPC(usually the wise blind guy trope) and multiple shades and flavors of characters.
The all white male game would standout way more than adding variety to NPC's.
None of that matter's though, it all goes back to the same point. Why not? It costs the same to paint a picture of a blind guy, brown guy, or gay guy as it does a straight white guy.
