If male hormones are not to be the sole criterion of what is the good, some form of societal sanction is necessary. That is why government is in the marriage business. It is in the interest of society to see to it that women and children are looked after if society is to remain civilized. That is why government must protect the weaker party (the wife and children) from the stronger (the male).
Fear not, you have an influential ally in the media:
Liberals stand for tolerance, magnanimity, community spirit, the defense of the weak against the powerful, love of learning, all American values worth conserving.
