This about dath ilan:
They think their negative utilitarians were pretty neuroatypical people, and possibly committing some sort of reasoning error in several cases if not all cases, for wanting to destroy dath ilan.
It's considered mildly infohazardous and you have to go onto the Ill-Advised Network to find anybody arguing about how bad a world would have to be, exactly, in order for 'well let's destroy that world' to be the correct tack according to whoever is talking.
Sort of an odd thing to debate, in a way, considering that a lot of opinion differences probably have to do with differences of utilityfunction. But sometimes, after all, people end up valuing different things after arguing about them. So the debates continue and of course never ever settle; and do moderate amounts of psychological damage along the way, on average, except for the 15% of people who actually come out of it feeling better, not in a particularly predictable way. Hence the Ill-Advisement.
