There are vast arrays of moral issues out there to struggle through. Some are easy (the Holocaust, racism), and some are hard (Just War theory, embryonic stem cell research). On most topics, people don't graduate to difficult areas of the subject until they get the easy questions right. Can we all agree that people who cannot say that drugging and raping a 13 year-old should be punished with jail time have failed a pretty basic test of moral common sense and are probably not qualified to opine on tougher issues until they master the basics? Just think of the issue of child-rape as the training wheels of moral dilemmas.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
