Not just that, but a community in the early 1900s...? before communism was even attempted at large scale? you don't have the "it's been tried and it didn't work" excuse to criticize him for.
He was a Communist until his death in the 1970s, but Communism is a pretty broad spectrum and his beliefs moved about it during his life. His public and financial support for Stalinism in France until the mid-1950s was a bad error of judgement.
