What was a belief held by civil rights activists during the war apex?

The correct answer is that The United States was fighting against an enemy who discriminated by race while allowing discrimination at home

They believed that the United States was using african-american soldiers and fighting discrimination and for equality in other countries worldwide, while at the same time they were segregating and violating the rights of their own people which meant that they were extremely hypocritical and had to first look into their own back yard.
