The mix of people at civil rights demonstrations sent a powerful message about the American civil rights movement. By bringing together people of different races, religions, and professions, the demonstrations showed that the struggle for civil rights was not just a matter of concern for African Americans, but a matter of justice and equality for all Americans. This diverse mix of people also demonstrated the strength of the movement and its ability to unite people from different backgrounds in a common cause. Ultimately, the message was that the fight for civil rights was not just a black issue or a white issue, but a human issue that affected everyone.
