the threat slavery would pose to free white labor and northern businessmen exploiting the newly colonized western territories, Whitman opposed the extension of slavery in the United States and supported the Wilmot Proviso. At first he was opposed to abolitionism, believing the movement did more harm than good. In 1846, he wrote that the abolitionists had, in fact, slowed the advancement of their cause by their "ultraism and officiousness". His main concern was that their methods disrupted the democratic process, as did the refusal of the Southern states to put the interests of the nation as a whole above their own. In 1856, in his unpublished The Eighteenth Presidency, addressing the men of the South, he wrote "you are either to abolish slavery or it will abolish you". Whitman also subscribed to the widespread opinion that even free African-Americans should not vote and was concerned at the increasing number of African-Americans in the legislature; as David Reynolds notes, Whitman wrote in prejudiced terms of these new voters and politicians, calling them "blacks, with about as much intellect and calibre (in the mass) as so many baboons." George Hutchinson and David Drews have written that "what little is known about the early development of Whitman's racial awareness suggests that he imbibed the prevailing white prejudices of his time and place, thinking of black people as servile, shiftless, ignorant, and given to stealing," but that despite his views remaining largely unchanged, "readers of the twentieth century, including black ones, imagined him as a fervent antiracist." Nationalism Whitman is often described as America's national poet, creating an image of the United States for itself. "Although he is often considered a champion of democracy and equality, Whitman constructs a hierarchy with himself at the head, America below, and the rest of the world in a subordinate position." In his study "The Pragmatic Whitman: Reimagining American Democracy", Stephen John Mack suggests that critics, who tend to ignore it, should look again at Whitman's nationalism: "Whitman's seemingly mawkish celebrations of the United States ... [are] one of those problematic features of his works that teachers and critics read past or explain away" (xv–xvi). Nathanael O'Reilly in an essay on "Walt Whitman's Nationalism in the First Edition of Leaves of Grass" claims that "Whitman's imagined America is arrogant, expansionist, hierarchical, racist and exclusive; such an America is unacceptable to Native Americans, African-Americans, immigrants, the disabled, the infertile,
