What was radical at the time about garrison and walker ideas about abolition?

William Lloyd Garrison and David Walker held radical views on abolition that challenged the prevailing norms of their time. Garrison advocated for immediate emancipation without compensation to slaveholders, rejecting gradual approaches and promoting a moral imperative against slavery. Walker's "Appeal to the Colored Citizens of the World" called for enslaved people to rise up against their oppressors, emphasizing self-defense and active resistance rather than passive acceptance. Their ideas pushed against both the complacency of moderate abolitionists and the broader societal acceptance of slavery, making them pivotal figures in the abolitionist movement.
