Most of us simply don't want any US politics to pollute the games we play. I don't care whether you have right-wing or left-wing views. If you try to blatantly inject your ideology into the game I will refuse to play it and simply ignore it. If you blatantly inject it into an old classic to make it more "modern" I will oppose it.
The problem is that the original games have at least one thing that I would consider right-wing ideology, and that would be racism presented as a good thing.
Specifically, we have characters who:
* are "good", according to their character sheets, and
* who are racist against the dark elf Viconia.
Specifically, I note that, in BG2, Aerie begs you not to let Viconia join, even though Viconia, as far as I can tell, has done nothing wrong. I also have read that, Keldorn, who is a *paladin* of all things (albeit one who doesn't get the abilities that normally distinguish a paladin from a fighter), also is prejudiced against the dark elf Viconia.
I could also point out the choice to make the one matriarchal society be evil, to the point of having slaves, to be right-wing ideology.
The BG games are an established franchise, and have been for 20 years. It has a world wide audience. Stuffing 4Chan and Tumblr politics and whatever Californian social-political hysteria anno 2016 into a middle chapter of the franchise is a rather huge miss.
As I said, the BG games already have right-wing politics in them.
Also, I could point out that SaGa Frontier, another games released around the same time, has an obvious lesbian couple, and it is not presented in a negative light. Then again, the SaGa series has always been atypical compared to other RPGs (I can cite the lack of levels and XP, for example).
