you take the position that [...] those people are not that bad.

I genuinely can't see where you get this except by deliberately misconstruing. I'm saying that "bad" is a nuanced position, and that we (collectively, including all the oppressed groups you're imagining) got through the last century or so in a much better position than we might have had the leaders we picked (yes, including Cheney) been more reflective of the ones ruling the rest of the world.

If you [...] see it from the point of view of [...] humanity as a species, then of course you're right.

Well... yeah? It sounds like you're admitting to some nuance, but want it not to reflect the world we actually live in? Well... it does.
