Moore was never as public about her involvement in the suffrage movement after that parade in 1913, because afterward she began participating anonymously, mostly through writing, using a pseudonym. During her stay in Carlisle, Pennsylvania, she admitted years later, she "wrote suffrage pieces for the Carlisle newspaper", which at the time appeared to be authored anonymously. Dr. Mary Chapman (University of British Columbia) argues that Moore was the writer of suffragist writings of the time in Carlisle news publications and that could be analyzed by examining her specific writing style alongside suffragist prose and poetry that were published in the "Carlisle Evening Herald" in 1915: "Many of the prosuffrage articles that appeared in the "Herald" exhibit Moore's characteristic reliance on quotation." Additionally, a letter appealing for the women's suffrage movement in the "Carlisle Evening Sentinel" is signed "Miss M.M.", which scholars believe could stand for Marianne Moore because "the absence of any other documented unmarried female suffragists in the Carlisle area with the initials M.M. make it likely that the "Sentinel" reader who coyly constructs a letter to the editor almost entirely from quotation is Marianne Moore". Moore's poem "Silence" (1924) also resembles the writing style that was seen in the "Sentinel" letter. Moore established herself on the surface as a modernist poet, and the common practice within the modernist circle of poets was to not engage with the politics of the time; but her writings displayed a "sophisticated political subtext".
