“We seek in one another the assurance that there is just one correct interpretation of the world, that everything is so simple that anybody can see it unless they're malicious or stupid or willfully ignorant; and we punish one another for proving with our differing conclusions that the truth is not that easy. We think we must suppress dissension to present the unified front we need to gain power over our enemies. But there are pro-life Democrats, pro-choice Christians, feminists who love their families, and conservatives who care about poor people.”
