"...that's probably a nonzero part of it but a larger part of it is that most demons don't want to murder people for the same reason most humans don't."

But they have no parents to teach them right from wrong.

" - do you believe that humans who grow up with abusive or neglectful parents all turn out to be murderers?"

Well, not all of them, but people are much better now than they were when it was common to hit children. (Child abuse discourse!)

It seems likely that's because trauma is bad, not because parenting is the only way to acquire morals.

So much discourse!

Are they going to treat everyone from Hazel as assumed-to-be-murderers biding their time? 

They probably don't want them as neighbors even if they don't all go in for murder. They might, like, attack people's housecats.

- it'd be kind of funny if the civilization that produces people who cannot live in harmony with other species or people from other backgrounds is 2180. Maybe everyone else won't want to live with people from 2180 because they're so closed-minded and xenophobic because of their harmful upbringings.

Is he saying that people from 1800 did not do horrible things to cats?

" - look, if you haven't figured it out by now - people are people. Some of them do horrible things to cats and some of them beat their children and it is perfectly reasonable to discriminate against people who do those things, the problem here is announcing that even if someone has never done anything wrong, if they're a member of a society or a species that you've heard a rumor does bad things, then clearly they want to do bad things and are just biding their time, and no amount of not doing bad things could possibly convince you that they don't actually want to. 

By all means don't live next to people who light cats on fire for fun. But if you could not even in principle be persuaded that someone hasn't done that and won't do that, then the bad person is you."

This statement, predictably, provokes Discourse.

They eventually conclude that he should warn for animal cruelty mentions.

He calls an end to the live feed and goes and asks Revelation's Maitimo how he can stand these people.

"- lighting cats on fire is legitimately a terrible thing to do, you know -"

"Nobody asked me to warn for literal actual slavery."

"Harder to imagine. Anyway, I handle it by finding all people extremely fascinating as strategic puzzles, I don't know if that works for you."

"They're just worthless and dumb."

" - can you figure out what I'd say and say it, is that an interesting strategic puzzle that doesn't involve engagement with worthless dumb opinions except at enough of a remove?"

"What would you have said to that -"

"That that was a good point, and you were also going to warn for slavery, because you wouldn't want to give the impression that animal cruelty is the only terrible thing discussed on your thread, and you also want to warn for engaging with lots of xenophobia and racism, since people will find those upsetting too..."

"I kind of miss not being able to light people on fire, because then I could say 'go die in a fire' without it coming across as a threat."

"Thank you for not saying that."

"Sure. You could just impersonate me with Polyjuice and do the videos."
