>>4001218 (OP)if we lived in a society composed exclusively of rational adults, i would consider it an acceptable ideology, but we don't.
the Nazis were less evil than ancaps, you know why? at least the Nazis believed in animal welfare. ancaps have this absolutely vile belief that the non-aggression principle should only apply to rational agents, meaning that animals and mentally disabled humans should not have protected rights. this means that, from an ancap perspective, sexually torturing mentally handicapped children to death is entirely permitted since the children aren't rational, so they have no rights and abusing them is no different than having fun with realistic human dolls. of course, most ancaps are psychopaths incapable of empathy or remorse, so they likely won't consider what i just described to be a problem. however, all humans are susceptible to becoming irrational, either due to brain injuries or age related illnesses, so instead of bringing up animals or disabled children, ask them if they'd be okay with their rights being dissolved if they received a brain injury or contracted Alzheimer's disease, and see if they're still willing to defend this repugnant position.
