Moore's combined major in history, politics, and economics and the suffrage involvement of professors and other students at Bryn Mawr exposed her to the women's suffrage movement, especially because it was a "unique period in the history of women’s college, as the values of progressivism, women’s education, and the ideology of separate spheres came together in a kind of perfect storm that created a climate for cultural change". Moore was involved in a "suffrage society", a chapter of the National College Equal Suffrage League, and she was present at most of their events. Notably, Moore wrote in her personal letters to her family that she attended lectures at Bryn Mawr by the well-known feminist Jane Addams and the British suffragette Anne Cobden-Sanderson. Of the American suffragist Anna Howard Shaw, she wrote: "Miss Shaw spoke last night on the Modern Democratic ideal. I couldn't say how she delighted me. No decent, half-kind, creature could possibly think of fighting suffrage if he or it had heard her arguments."
