A good example is the old rpg Rifts. The main book vilifies the Coalition as this horrible, monstrous regime that is wholly based on the Nazis. But the idea that they are totally evil because they hate non-humans is so silly in a setting where hordes of human eating monsters have literally poured through portals to wipe out most of humanity that I am not sure why they decided to make it their main villain.
I get that the coalition is supposed to be the extreme, that they went beyond simply hating nonhumans to using them as a reason to persecute everyone, but it is still such a strange way of taking on a real world subject. In a setting where there are tons of creatures who will eat you, or your soul, or flay your family alive, or use you as a living battery for their magic, the true villain is racism? IT just seems like a strange viewpoint that is far more based on real world views, than anything that would come out of the actual setting of the game.
In defense of RIFTs, while I agree with you, I still have some of the old source books and if you read through it there is a bit more nuance to be had. If you read out beyond the core book and get into the history of the Coalition, it originally wasn't so extreme as it is at now, yes, they shot anything that came out of a rift for very understandable reasons, but it was radicalized by power seeking aristocrats to cement their power at a critical point in its political development. The way I read it, the lesson isn't that "the real villain is racism" it's "the real villain is extremism/demagoguery/fascism". You get the impression that you can believe either:
1) The Coalition is just pure evil
2) The Coalition is a Necessary Bad Thing that has the potential to be a Good Thing but good flipping luck fixing it
It's sort of the same vibe as the Imperium of 40K, it's a horrible organization, but the world it exists in sucks so bad you can understand why and how it developed and why it's successful. Its values and modus operandi are deplorable, but the world it operates in is so extreme you understand why it's there and why people feel the need to support it; it's a black spot with some gray swirled around the edges.
It is an interesting idea, the Coalition, because it's very easy to believe that someone who lives in Chi-Town whose whole life is controlled by propaganda probably believes that everything outside the walls is 100% horrible and an existential threat to humanity. On the other hand if you live in a frontier settlement where you probably conduct life sustaining trade with magic-users and non humans, you might well be a Coalition citizen but your POV is probably quite different. I've always imagined it as full of some True Believers, but mostly scared, helpless people whose alternatives are to carry a flag for the fascists in the awesome black skull shaped death robots that swoop in and kill all the horrible monsters and, well, being eaten by the horrible monsters that laugh at your little laser rifle because you didn't carry the flag for the fascists in the awesome black skull shaped death robots.
That's actually kind of the point of the new Savage Worlds edition, was the other forces in the setting cooperating to give those people a viable alternative.
It's worth remembering the Coalition themselves are
tremendous hypocrites, they have no problem using psychics, mutants, non-humans etc. to advance their own agendas under the banner of "it's okay when WE do it" and that's solidly in the lore without head-canon (see Dog Boys). I've always portrayed them as having spies and traitors in enemy factions. That doesn't make them not evil, rather it makes them a little bit less cartoonish and a bit more realistic.
There is some nuance there to explore if you really want to, but I would say it depends a lot, possibly too much, on the Gamemaster to add some fiber to it and make it a more believable depiction. If you're just reading the core rulebook I get that you do not get that impression of nuance or believability anywhere. Siembieda... he's a very creative writer, but he's not a novelist he's a world builder. That roughness is part of the charm of RIFTS, because it's raw and it's somebody's unfiltered vision and I love stuff like that even when it is a bit unrefined, but it does mean you have to work at it harder to make an actual narrative.
But then again, that's any game. You can have flat, irredeemable and unbelievable villains if you want, that works for some games sometimes it's even best. Or you can put the work in and make villains that players can understand the motivations of, which actually makes the players hate the villains even more in my experience.
