What argument does King make supporting the need for direct action?

King's intent was not so much to support the argument, but rather to explain it. He wasn't really offering arguments, he was offering explanations, and ultimately warnings of what might or might not lay ahead. The white clergy voiced concerns over the movement, and King defended it. He cited the necessity of his presence in Birmingham, and he explained the concept of non-violent demonstration.... the direct action for which he willingly accepted jail in order to "arouse the conscience of the community over its injustice." King's explanations and call for the community and nation to love one another was not only succesful, but a logical, intelligent validation of the necessity for civil rights reform.
