You are a very sad man, if you think that lust is what motivates all men. And if you think that, then you should be in favor of contraceptives, even at your expense.

You exemplify John Kenneth Galbraith's observation, "The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness."
