Final answer:
King's advocacy for nonviolent protest is one of the most compelling parts of his argument.
Step-by-step explanation:
Among the parts of King's argument that I find most compelling are his advocacy for nonviolent protest. King believed that peaceful means were essential for creating meaningful and lasting change. He drew inspiration from figures like Mohandas Gandhi and Henry David Thoreau, who used nonviolence to achieve their goals. For example, King states in his 'Letter from a Birmingham Jail' that 'nonviolent direct action seeks to create such a crisis and establish such creative tension that a community that has consistently refused to negotiate is forced to confront the issue.' This demonstrates his belief that nonviolent protest is a powerful tool for bringing awareness and change to social issues.
