The "secret to happiness" is to not think of ourselves as sperm donors and/or baby ovens. Reproduction is over-rated and is NOT, as many have been led to believe, a way of achieving immortality. A person's DNA is NOT that "special" and it is more likely that your kid will CAUSE cancer or DIE of some disease than CURE it.
I hope i offended at least one person who wasn't already offended by something i'd said previously. Personally i find the above things quite disgusting myself and think more people need to hear these ideas articulated and see them written down in a non-apologetic tone.
