>So presumably, if some foreign power invaded the US next week, violently exterminated most of the population, and herded the survivors into a few tracts of land, you would be fine with that?

I can tell you that I wouldn't expect to stand on my doorstep, facing the men with guns, saying, "ah, ah, ah, I own this land!" and have them turn away.

We do horrible things to other people, no doubt about it. Even worse, this specific moment in history isn't unique. So it goes.
