So, I think this is part of a MUCH larger discussion about settings, fantasy ones in particular perhaps, but a lot of settings in general. They are incredibly 'gamist'. I mean, any unbiased reading of human history will lead us to the conclusion that some happy mixture of races, ideologies, egalitarianism, and gender equality is the greatest fantasy of all. Maybe some of those things are realistic, surely they have all existed to a degree in real human history. However it is vastly more likely that what would normally be encountered would be profoundly different from that. BUT we can only work within the model of imagined social/cultural/political acceptability to modern people. My point being that all these settings are so utterly gamist as to make any appeal to 'realism' moot.
