The battle wasn't trivial. It was fundamental. I don't like the gender implications of that label, so in my paraphrase here I'll call it conservatism. Every human being is expected to be able to summon such strength, which is developed through respect for and obedience to authority. Strict behavioral norms are essential, because moving outside permissible paths not only is personally immoral, it calls into question the whole moral order.
Deviants tempt others by making deviance look safe, normal, even attractive.
People in positions of authority are especially required to demonstrate and enforce proper behavior. Punishment for violating authority is the main way in which authority is maintained. If you see the world this way, you not only want this president removed, you have been appalled by him all along, by his draft avoidance, his not-inhaling, his sensual appetites, his compassion for social deviants. This undisciplined man was never an acceptable leader of our nation or a model for our children. His tawdry affair, his ignoble attempts to hide it, his unwillingness to shrivel up in shame are just the last straws in a career of moral outrageousness.
