Final answer:
Criticism of the Birmingham protests included the provocatively non-violent tactics inviting violent police responses and the argument by some white leaders for slower progress on desegregation. The use of children in protests also drew significant backlash after the excessive brutality they faced.
Step-by-step explanation:
The criticisms of the political demonstrations and protests which took place in Birmingham in 1963 primarily centered around the violent responses they provoked, particularly from law enforcement. First, the strategic use of non-violent protests led by the Southern Christian Leadership Conference (SCLC) and Martin Luther King, Jr. was criticized by some for inviting violent reactions, as seen when peaceful protestors were met with aggressive actions from the police, including the use of fire hoses and attack dogs against children.
Secondly, the demonstrations were critiqued by some white religious leaders and city officials who believed that these demonstrations would disrupt peace and that civil rights activists were pushing for desegregation too hastily. Moreover, criticism arose from the use of children in mass demonstrations, the most notable being the Children's March, which led to the arrest and mistreatment of hundreds of young protesters, prompting national outrage and criticism.
