Nah. Game is full of such little things, stuff you can't help but notice and add one on top of the other after thousand of hours.
But even that example provided, why on Earth should Hosea tell Arthur, while Lenny isn't even there, that Lenny is "He's the best of us all, we're luckly to have him", other than Rockstar trying to score some woke points?
Lenny is a regular ass member, nothing special to him at all other than the fact he's black.
In a real game, like the original RDR, Lenny would probably be made fun of from time to time, or be object of racist jokes within the gang, including main characters. Which would then make what happen to him hit so much more, for both players and game characters. But that would require balls.
Sure, Charles as well. Nothing really major, but still little things and there.
Things is, these "little things here and there" were not there in Red Dead Redemption. Every single line had artistic meaning, there was no influence.
Some can be bothered by these minor things, others not. But I will always be bothered by things that take me out of the game, forcing my mind to go from 1899 America to the liberals working at Rockstar.
