What I fail to comprehend is how you've redefined the word nuance in such a way that black & white hard lines between good and evil are more nuanced than shades of grey with smaller variations possible within the same species. That's what I'm failing to understand.
OK, so we can at least move on from that other stuff but this is a misrepresentation of what I'm saying.
Its not me who is redefining the word nuance. Everyone is now good. Not 'everyone has the potential for good'. EVERYONE IS GOOD.
Before, yes there were species options that were 'bad' and some where 'good' and it was up to the player to either buck the trend, or go along with it. Post Tashas? You are good. Your friends are good. Bob the Orc is your neighbor. The Tiefling? Well his ancestors actually won the Blood War, on the Good side. Hes good too. Those Duergar? Not a problem, oh and we dont directly reference the fact they were enslaved, we dont talk about that anymore see.
This isnt a nuanced (subtle, the word means subtle) and I'm not the one changing the definition. Before, there was variation. Now, 'everyone is good'. Wizards is literally slamming us upside the head that their disnified view on their own lore and settings can ONLY be presented as 'You are good, heros, doing good heroic things.'
That isnt nuance my man.
The irony is, my BG3 Paladin was the most noble, most shining, most good, folk hero, savior of the weak he could possible be, from start to finish. Why? Because he contrasted with the actions and behaviors of the people around him. EDIT: And now that I think of it, so was my Tiefling Paladin with the -2 Cha penalty decades ago, because no recent edition of this game actually forced players into the straight jacket some STILL believe exists.
If everyone is shining rainbows of goodness? Well thats not a very nuanced setting.
