What about killing all but a handful of mosquitoes, fire ants, or other insects? I might suggest we stopped too soon
Why not bacteria? We can kill those by the trillions.
That's the power of only seeing one story, minus context of what the rest of the world was like. Would you also call the history of what native american tribes did to each other evil? Or was it on par with the brutality of the times?
You're misusing that fallacy here, but I don't fault you, because my point is subtle. My claim isn't that their point is invalid because they're hypocritical about native american history, my claim is that their gauge of evil is miscalibrated, because only a certain perspective of history is amplified to this degree, minus the historical context that puts it on par with the times.
They did regular brutality. Attack another tribe, kill like 5% of them, rape etc. everyone did that. No one really wiped out entire species.
