I agree with you, slapping a veneer of diverse identity on a character post-facto is often just performative bullshit. At best it’s bad representation, at worst it’s cynical pinkwashing and pandering for profit.
But that’s not a distinction I have ever seen an “anti-woke gamer” railing against.
What I do see them railing against is any representation in games that does not pander to their own personal preferences.
Did you not encounter any of the backlash to Ellie’s sexuality? Honestly I think FNV only escapes a lot of that kind of vitriol because it was released pre-gg.
