The Amish live in communes where as far as I know they practice what could be considered a form of communism. They also live in ways that are self sufficient and sustainable. However, they have been criticized for their conservative religious views (which come with unpleasant things such as homophobia, etc) as well as their complete denouncing of anyone who leaves, which many consider symptoms of a cult. Another thing is that you have to follow their specific religion to live in their community.
I’ve never heard any communists comment on them, so what do people in this community think of the Amish and their lifestyle?
They’re proof positive of sustainable communist style economic communities, but most bona fide, card carrying communists like myself would criticise them for their narrow, religiously driven way of life. Communists aren’t dedicated to upholding one set of moral values over another, they’re committed to the political line that ensures the highest degree of egalitarianism possible. Whatever ensures such an egalitarian society is something we’ll support, even if that means suppressing views that are anti-egalitarian. Think Karl Popper’s paradox of tolerance, it’s basically the same idea in effect.
