Actually there are a few Shakers still around. Very small numbers. Very few converts. But hey, what ever floats their boat. You won’t hear any complaints from me. Like you said, they did not use abortion or other medical ways to controls of fertility, just sleeping in different dorms. One thing that can’t be said of them is that they are Fifty Shades of What ever if you get my drift.
I don’t think they are “real” Shakers. The Shaker “Council” made a decision not to except any new members long ago, and the last pre-decision member died in the 1980s, iirc.
I say “pre-” because they apparently still took in the odd lost soul now and then, but not for membership.
