Baldwin apparently changed his views on communism, at least Soviet communism. See my post #4.
The archetypal Hive institution was the American Civil Liberties Union. In 1927 its long-time leader, Roger Baldwin, visited the Soviet Union, where he said there was no need for a civil liberties union, since the “working class” already ruled in Russia. Later, two top officials of the American Communist Party would be appointed to the national board of the ACLU. Subservience to Stalin was fully compatible with devotion to American “civil liberties” — as defined by the ACLU.

Lefties like Emma Goldman and Bertrand Russell denounced Soviet Communism pretty early as a betrayal of socialism's ideals.
