Coe was involved in the American Committee for the Protection of Foreign Born.[9] In the later part of his life he became sympathetic to Marxist ethics,[2] stating that "Marx raised the fundamental ethical questions whether it is humane or just that a man's sustenance should depend on his contributing by his labor to the private profit of another".[10] He considered that "we are not done with Marxism when we weight the merits and demerits of the Soviet government, nor when we choose between communist and anti-communist ideology" due to this ethical concern.[11] He was one of 450 figures to sign a statement defending the "constitutional rights of the Communist Party of the United States"[12] and was involved in the 'National Non-Partisan Committee' to defend those in the Smith Act trials of Communist Party leaders.[13]
