Question

Quizplus · Accepted Answer

Many white northerners who opposed slavery were still racist and believed in the supremacy of the white race. They may have opposed slavery because they saw it as detrimental to white labor or as a violation of individual rights, rather than because they cared about the wellbeing of enslaved people. This underlying racism made it difficult for them to fully commit to the abolitionist movement.
