The unofficial symbol of black feminism in the late 60s, a combination of the raised fist of Black Power, and the astrological symbol for Venus, denoted an intersection of ideals of Black Power and militant feminism. Some ideals were shared, such as a "critique on racial capitalism, starting with slavery". Despite this, black feminism had reasons to become independent of black nationalism, according to some critics, because it had achieved only a niche within the generally sexist and masculinist structure of black nationalism.
