New York Postmaster Edward M. Morgan. Socialism Harrison was an early advocate of the Georgist economic philosophy and later clarified that he had believed Georgism was the same thing as socialism. In 1911, after his postal firing, Harrison began full-time work with the Socialist Party of America and became America's leading Black Socialist. He lectured widely against capitalism, campaigned for the party presidential candidate Eugene V. Debs in 1912, and founded the Colored Socialist Club (the Socialist's first effort at reaching African Americans). He developed two important and pioneering theoretical series on "The Negro and Socialism" for the socialist newspaper the New York Call and for the socialist monthly International Socialist Review. In these articles Harrison outlined a materialist analysis of racism, arguing that it resulted from "the fallacy of economic fear" and economic competition, and that capitalists had an interest in maintaining economic discrimination based on racism, as "they can always use it as a club for the other workers". He maintained that it was the principal "duty" of the Socialists to "champion the cause of the African American and that the Socialists should undertake special efforts to reach African Americans as they had done with foreigners and women." Perhaps most importantly, he emphasized that "Politically, the Negro is the touchstone of the modern democratic idea" and that true democracy and equality implies "a revolution... startling even to think of." Harrison moved to the left in the Socialist Party. He supported the socialistic, egalitarian, and militantly radical Industrial Workers of the World (IWW). He was a prominent speaker along with IWW leaders Bill Haywood, Elizabeth Gurley Flynn, Carlo Tresca, and Patrick Quinlan at the historic 1913 Paterson Silk Strike of 1913. He also supported IWW advocacy of direct action and sabotage. He commended the interracial, IWW-influenced, Brotherhood of Timber Workers efforts in the Deep South. Despite his efforts, Socialist Party practice and positions included segregated locals in the South and racist positions on Asian immigration. Harrison's position in the Party was also affected by his alignment with its left-wing and the IWW, who were engaged in factional struggle with its right-wing faction: many leftists exited after Haywood (who had been a member of the SPA's executive committee) was expelled from the Party in 1912. The Socialist Party of New York was led by Morris Hillquit, a prominent figure on the right, and party leaders in New York City began
