How the forget is that arbitrary? If I shoved you through another person's gaping axe wound I think you'd put that on your calendar or some stuff.
Because you're trying to use logic to win a philosophical argument when logically your argument is flawed.
I like how you compare an unwanted and underprivileged child to a masterpiece. Nice.
Except that all genocides in the past have been unfounded. The jews have been the target of this many times. national socialist Germany blamed them for destroying the economy and during the Black Plague they were accused of poisoning the wells with disease. The future "genocides" will be based on things that actually make sense. Instead of taking the hedge clippers to the head of the topiary, we'll trip the brown leaves.
Or like, find a way that doesn't involve the mass extermination of people. To the Germans, the holocaust made sense, even though it was nothing short of a despicable crime against humanity. How does that differ from say if the government decided that blind people had to go because they contributed nothing to society, and then killed all the blind people. Would that be justified in your eyes?
