how do you make a fat person physically superior besides giving them a weight bench?
it's impossible to kill society especially in terms of reproduction, reproduction is a social process

Humans are social animals.
Sex should be reproductive.. or maybe it shouldn't be reproductive because your anarchist idealism will become harder and harder to acheive with overpopulation problems. Most people probably don't think that everytime they bring a child into the world they are fucking the world over. Especially as long as they have more than one per person.
I hate assholes who have like ten children. Quit hogging all the procreation

PLus most people who have ten children probably won't even raise them well and they are just raising more cunts to fill the world with cunt attitudes.
