Abstract
A common analysis of current U.S. politics identifies the main problem as ideological polarization leading to government dysfunction, and moderation as the main solution. But drawing from Martin Luther King Jr., I contend that the main problem is sectarianism or us-them thinking, leading to injustice, and the main solution a social movement of love and justice. Notably, while many call for deemphasizing ideas, my solution calls for more emphasis on ideas. The purpose of government is justice. The moderation solution, although superficially value-free, implicitly values the status quo or gradualism over justice, reflecting King’s “white moderate, who is more devoted to ‘order’ than to justice.” Sectarianism is bad for involving animosity toward outgroup members and undermining critical thinking, resulting in decision-making based on group power rather than rationality and justice. The moderation solution resembles sectarianism in encouraging decision-making based not on substance but relative to where others stand. Moreover, responding to injustice with moderation often involves capitulation to it. Counteracting sectarianism requires caring across group lines and making political decisions based on justice. A social movement, appealing to high ideals and broad solidarity—like King’s “extremism” for love and justice—is necessary to transform policies and our political culture.
