Now admittedly half the people born are below average intelligence, but I sure don't see half the population acting like they have any intelligence at all much less above average. The one thing I have found is most people are willing to listen and even learn. Instead of whining about how narrow minded and ignorant somebody is try opening their eyes. Do it gently and with understanding and remember they will be having to loose old baggage and probably resent you for trying. Otherwise we will continue to spiral back down into fear, ignorance, oppression and superstition.
Fatherhood is an old and fairly well understood institution.
Fatherhood has always been one of the risks you took for having sex. And through out history, when birth control has been a gamble at best, it has been a rather likely outcome. Being a species that works in groups and forms societies for the protection and betterment of its members we implemented rules to help make men be responsible fathers instead of just sperm donors. Also there have been trends toward patralinial disbursement of property. Let's face it if your going to impose a patralinial paradigm you have to enforce some type of reproductive fidelity, because until recently there really was no way of knowing what male fathered what child.
