Tiny kittens are also cute and haven't even done anything to death yet. But if you accidentally lock one in a car and it suffocates, that's merely unfortunate, and should probably not be a crime. The same is true for infants and all other non-person life. If you kill a kitten for some reason other than sadism, well, it's unfortunate that you felt that was necessary, but again, they're not people.

Yeah, I get it, you don't consider babies people and I do. So pretty much we just throw down (ie. trying to reason each other into having the same values as ourselves would be pointless). You vote for baby killing, I vote against it. If there is a war of annihilation and I'm forced to choose sides between the baby killers and the non-baby killers and they seem evenly matched then I choose the non-baby killers side and go kill all the baby killers. If I somehow have the option to exclude all consideration of your preferences from the optimisation function of an FAI then I take it. Just a plain ol' conflict of terminal values.
