I hate to defend "Pangs" but I believe that the intention wasn't to show that the "savages" deserved being conquered. It was to show that sadly pretty much each and every country on Earth did such atrocities at one point or another and you can't undo those things. Being politically correct won't magically give the dead native Americans back their lives and land. Delving too much into the past is a recipe for disaster - just look at the Balkans where every state has territorial claims towards its neighbours, the patriots dream of Mega-[Insert Country Name] and hate other nationalities for what they supposedly did to their ancestors hundreds of years ago. Let's face it, anyone can claim that his country or ethnic group has been screwed up by some other country or ethnic group at some point. Buffy and Willow can't really do anything for the Chumash spirits anyway and the latter aren't in the mood for negotiations. And I really don't think people should feel guilty for what their ancestors did. Acknowledging it, yes, but guilt?
They are? One guy goes for revenge, that's about it. Okay, he summons a few buddies to help him but we might as well claim Scandinavians needed to change radically just because Anya became a vengeance demon and Olaf took splendidly to life as a troll.
whilst the Chumash are ultimately portrayed as needing civilizing and thus the colonial power vindicated.
