Native Americans were savages, constantly at war with eachother, who practiced ritual sacrifice and slavery. It's a very good thing they were defeated.

I'm unaware of Hawaiians story but prized lands tend to be taken by modern forces and that is an old story.

Africans practice slavery still, have always, and no amount of Western influence has inspired those peoples to raise themselves up. Still, monetary colonialism via Fiat is a scourge that probably prevents any such upwards mobility and will be destroyed by #Bitcoin, granting these peoples a better chance as self determination.

The Crusades was good.
