For instance, the Civ games are basically Whig History: The Game, presenting liberal capitalism as the ideal end point for all societies. It even includes uncivilized "barbarian tribes" whose sole purpose is to be exterminated so you can take their land for the glory of capitalism.
I despise the grey jedi shit. The whole point of the force is that there actually is a clear moral good and evil, and using power to hurt and oppress people for personal gain is both wrong, and self-annihilating. The whole purpose of Darth Vader is to show that if you use power to hurt people you'll inevitably turn in to a monster, and the only way to save yourself from that is to reject your power. Luke doesn't win by defeating Vader in combat, he wins by refusing to give in to his anger and rage, recognizing that if he did so he'd end up becoming a monster like his father. And when Vader see's him reject that path he has a moment of self reflection and decides to stop being Darth Vader.
But it also doesn't pussy foot around with any liberal shit. George Lucas said it's righteous and just to blow up the American-British-Nazi empire and let little teddy bears eat them.
