"They should not be allowed to breed..."

[fpb]

Anyone can say anything in a fit of anger. But to make such a claim in deadly earnest shows that you want to be God, deciding who lives and who doesn't - and that is the Devil's posture. Plus, on the practical side, you are postulating a state bureaucracy to decide who is allowed to breed and who is too - moronic, diseased, drugged, whatever - to have children. One doesn't have to be a state-hater to see that this is a very bad idea indeed.
