Frederick Douglass believed that Americans were prevented from fully living up to the principles of the constitution because of slavery and the racism and discrimination that it fostered. He argued that the institution of slavery not only violated the inherent rights and freedoms guaranteed by the constitution, but also perpetuated a system of oppression and inequality that undermined the core values of the nation.
