	Moore was a "racist." His racist ideas were reinforced by his reading Joseph Widney's 1907 "Race Life of the Aryan Peoples", a book recommended to him by Theodore Roosevelt, which Moore proceeded to review favorably. He was a defender of the Ku Klux Klan and a proponent of lynching. Additionally, Moore was francophobic for racist reasons, lambasting the French for "intermarrying with the Indians and treating them as equals" during the French colonization of the Americas.
