Answer:
Abolitionists from the beginning of American independence saw slavery as a cruel practice on other human beings. They despised that Africans were taken from their native countries and forced to work in cruel conditions in plantations. This does NOT mean that abolitionists saw Africans as equal to them. In fact, the majority, including Africans themselves, believed that Africans could be most prosperous in Africa (there was later a project to bring African Americans to Liberia). They believed that it was impossible for 'white' and 'black' Americans to live peacefully in the same society.
