King's stress on love and nonviolence was powerfully effective in building a sympathetic following throughout the nation, among whites as well as blacks. But there were blacks who thought the message naive, that while there were misguided people who might be won over by love, there were others who would have to be bitterly fought, and not always with nonviolence. Two years after the Montgomery boycott, in Monroe, North Carolina, an ex-marine named Robert Williams, the president of the local NAACP, became known for his view that blacks should defend themselves against violence, with guns if necessary. When local Klansmen attacked the home of one of the leaders of the Monroe NAACP, Williams and other blacks, armed with rifles, fired back. The Klan left. (The Klan was being challenged now with its own tactic of violence; a Klan raid on an Indian community in North Carolina was repelled by Indians firing rifles.)

Still, in the years that followed, southern blacks stressed nonviolence. On February 1, 1960, four freshmen at a Negro college in Greensboro, North Carolina, decided to sit down at the Woolworth's lunch counter downtown, where only whites ate. They were refused service, and when they would not leave, the lunch counter was closed for the day. The next day they returned, and then, day after day, other Negroes came to sit silently.

In the next two weeks, sit-ins spread to fifteen cities in five southern states. A seventeen-year-old sophomore at Spelman College in Atlanta, Ruby Doris Smith, heard about Greensboro:

When the student committee was formed… I told my older sister… to put me on the list. And when two hundred students were selected for the first demonstration I was among them. I went through the food line in the restaurant at the State Capitol with six other students, but when we got to the cashier she wouldn't take our money… The Lieutenant-Governor came down and told us to leave. We didn't and went to the county jail.

In his Harlem apartment in New York, a young Negro teacher of mathematics named Bob Moses saw a photo in the newspapers of the Greensboro sit-inners. "The students in that picture had a certain look on their faces, sort of sullen, angry, determined. Before, the Negro in the South had always looked on the defensive, cringing. This time they were taking the initiative. They were kids my age, and I knew this had something to do with my own life."

There was violence against the sit-inners. But the idea of taking the initiative against segregation took hold. In the next twelve months, more than fifty thousand people, mostly black, some white, participated in demonstrations of one kind or another in a hundred cities, and over 3,600 people were put in jail. But by the end of 1960, lunch counters were open to blacks in Greensboro and many other places.

A year after the Greensboro incident, a northern-based group dedicated to racial equality-CORE (Congress of Racial Equality)-organized "Freedom Rides" in which blacks and whites traveled together on buses going through the South, to try to break the segregation pattern in interstate travel. Such segregation had long been illegal, but the federal government never enforced the law in the South; the President now was John F. Kennedy, but he too seemed cautious about the race question, concerned about the support of southern white leaders of the Democratic party.

The two buses that left Washington, D.C., on May 4, 1963, headed for New Orleans, never got there. In South Carolina, riders were beaten. In Alabama, a bus was set afire. Freedom Riders were attacked with fists and iron bars. The southern police did not interfere with any of this violence, nor did the federal government. FBI agents watched, took notes, did nothing.

At this point, veterans of the sit-ins, who had recently formed the Student Nonviolent Coordinating Committee (SNCC), dedicated to nonviolent but militant action for equal rights, organized another Freedom Ride, from Nashville to Birmingham. Before they started out, they called the Department of Justice in Washington, D.C., to ask for protection. As Ruby Doris Smith reported: "… the Justice Department said no, they couldn't protect anyone, but if something happened, they would investigate. You know how they do…"

The racially mixed SNCC Freedom Riders were arrested in Birmingham, Alabama, spent a night in jail, were taken to the Tennessee border by police, made their way back to Birmingham, took a bus to Montgomery, and there were attacked by whites with fists and clubs, in a bloody scene. They resumed their trip, to Jackson, Mississippi.

By this time the Freedom Riders were in the news all over the world, and the government was anxious to prevent further violence. Attorney General Robert Kennedy, instead of insisting on their right to travel without being arrested, agreed to the Freedom Riders' being arrested in Jackson, in return for Mississippi police protection against possible mob violence. As Victor Navasky comments in Kennedy Justice, about Robert Kennedy: "He didn't hesitate to trade the freedom riders' constitutional right to interstate travel for Senator Eastland's guarantee of their right to live."

The Freedom Riders did not become subdued in jail. They resisted, protested, sang, demanded their rights. Stokely Carmichael recalled later how he and his fellow inmates were singing in the Parchman jail in Mississippi and the sheriff threatened to take away their mattresses:

I hung on to the mattress and said, "I think we have a right to them and I think you're unjust." And he said, "I don't want to hear all that shit, nigger," and started to put on the wristbreakers. I wouldn't move and started to sing "I'm Gonna Tell God How You Treat Me" and everybody started to sing it, and by this time Tyson was really to pieces. He called to the trusties, "Get him in there!" and he went out the door and slammed it, and left everybody else with their mattresses.

In Albany, Georgia, a small deep-South town where the atmosphere of slavery still lingered, mass demonstrations took place in the winter of 1961 and again in 1962. Of 22,000 black people in Albany, over a thousand went to jail for marching, assembling, to protest segregation and discrimination. Here, as in all the demonstrations that would sweep over the South, little black children participated-a new generation was learning to act. The Albany police chief, after one of the mass arrests, was taking the names of prisoners lined up before his desk. He looked up and saw a Negro boy about nine years old. "What's your name?" The boy looked straight at him and said: "Freedom, Freedom."

There is no way of measuring the effect of that southern movement on the sensibilities of a whole generation of young black people, or of tracing the process by which some of them became activists and leaders. In Lee County, Georgia, after the events of 1961–1962, a black teenager named James Crawford joined SNCC and began taking black people to the county courthouse to vote. One day, bringing a woman there, he was approached by the deputy registrar. Another SNCC worker took notes on the conversation:

In Birmingham in 1963, thousands of blacks went into the streets, facing police clubs, tear gas, dogs, high-powered water hoses. And meanwhile, all over the deep South, the young people of SNCC, mostly black, a few white, were moving into communities in Georgia, Alabama, Mississippi, Arkansas. Joined by local black people, they were organizing, to register people to vote, to protest against racism, to build up courage against violence. The Department of Justice recorded 1412 demonstrations in three months of 1963. Imprisonment became commonplace, beatings became frequent. Many local people were afraid. Others came forward. A nineteen-year- old black student from Illinois named Carver Neblett, working for SNCC in Terrell County, Georgia, reported:
