"The immorality of procreation praised as conscious is this: here the crime of making a man, to introduce more evil and pain in the world is not made unconsciously in ecstasy and drama in the darkness of copulation, but is coolly premeditated, people then are no longer cautious and repeat the act until they reach the goal. But there is something even worse: artificial procreation, semen ice, where without the manipulator and the belly person horrified by what they do, lacks even the delight that is some extenuating circumstance."
