It's always been impossible because the gaming industry is large enough that anything will cause outrage from at least one loud person. The real question you should ask, "Is it impossible for a game to have a black protagonists without the protagonist's race being a politically or socially motivated?" The answer to that is still yes but it's the dev choice. Movies have had black leads for years and nobody cares because those movies didn't have a black person so the director can get brownie points.
Very few people (other than the boogie men that resetera told you exist) care about race and gender in video games. A lot of people get frustrated when race and gender is used as a way to get brownie points instead of as a way to increase the quality of the story or game itself.
Clearly you viewed the BFV outrage from the outside looking in. Very very few people were upset at the inclusion of women in BFV. I'm not going to spend my time explaining the issues people had with BFV to you because you have clearly convinced yourself a false narrative is reality. Just a quick thought experiment for you though, try to think why BFV sales are so low and why the game did a drastic change in visuals e.g. cosmetics and art style from the original reveal to launch.
No one assumes that other than your fun little straw men.
The middle ground comes when devs don't include people of color solely for identity politics. Another thought experiment for you. Try to think how many people are upset that Tomb Raider stars a woman.
Very very few people were upset at the inclusion of women in BFV??!! Check the thread on here. Lot's of people were.
The assumption you make that "movie directors don't include black leads to get brownie points but rather to increase the quality of the product" implies that game directors ONLY include black leads to get brownie points. Unless I'm misunderstanding you.
You even then say it's impossible for a game director to include black leads without it being politically or socially motivated.
You've just highlighted my whole point really well for me. It's hard being a game director!! If you go with a black female lead for your new action game people give you shit for trying to score brownie points and doing it for politically motivated reasons. If you're a film director and use a black female lead your doing it to enhance your creation or vision. This is your own logic. How can the game director "win". They need to demonstrate their inclusion of a black) female character is for artistic reasons m but how could we ever know?
"Very few people care about race and gender in games".
Bullseye!! This is the very crux of the issue. Very few (white) male gamers care about race and gender in games because we (me) are already well catered for. We are not underrepresented in the medium. As a white straight male myself why would I be wanting more representation of characters I can identify with. Like 90% + games have male leads but half our population are female. Those who say "I don't see the problem here at all" aren't the people affected by the problem... that's what's behind a lot of gamergate culture.
It's historically understandable as throughout most of the history of gaming, the vast majority of gamers were male. But that's changing. If you're a female gamer wouldn't it be great to play as a female character? Or a black person to play as a black person?
