> The survival of my loved ones -- and that's a category that can go across species -- is absolutely important to me. The survival of evil space Nazis? Eh.

The idea is that if it's between all people dead, or all people except evil space Nazis, I'll take evil space Nazis. Just because they are evil space Nazis now doesn't mean they will be hundreds of years from now, but they'll never get that chance if all humans are gone.

Human history is largely a story about bigoted, insular racist violent psychopaths becoming slightly less of each of those things over time. I don't see why that trend won't continue in general even if we hit a local maxima of fascist oppression from time to time (as this would be).

Because I love people, I can understand the concept of loving people in general, and want other people to be able to experience that. Human extinction means that nobody might ever experience that again, and I think that's a shame, and will do what I can to prevent that type of outcome.

> Many of us appreciate things that aren't truly keen from an evolutionary perspective.

There isn't appreciation of that type without people to do the appreciating. Your ability to appreciate it is provided by our current circumstances. I think keeping those circumstances active is worthwhile. Otherwise you are taking more than you are giving to the species as a whole, which is unsustainable if too many people do so. Even if you don't care about how sustainable it is, you would be riding on the hard work the rest of the species is putting into the system to propagate. Don't be taker.

If it's up to me between no humans and evil space Nazis? I'll take no humans every time. We're a stain on the face of existence, we pollute and destroy our environment, we abuse our own species and others as a matter of course, and we're just overall destructive. The only thing that changes that is that sometimes one or two people rise up and decide that they will resist that status quo and do something about it. To allow a group of people who are evil in the conception of a default-destructive species to be the only ones left? Better to let the species die.

I think you are deeply misjudging the complexity of the human experience and being particularly blind to or biased against our collective history. If you spend any amount of time talking to people or even just reading the personal writings left to us by the ages you quickly realize that everyone who has ever lived is no different from yourself, we simply made different choices based on the information available to us, for good or evil. Anyone, given the right conditions, is capable of being a monster or a saint.
