At first I was thinking Amish brain control space lasers was the best oxymoron I've heard in a long time, but upon reflection: the biggest problem the Amish have with technology is the degree to which it networks them with the English.

If they had their own secret crater on the dark side of the moon (separate from the one in Iron Sky of course), due to the gravity wells involved it would have to be self-sufficient, so even if they had had to pay some Mennonites to launch the self-replicating factories that built the brain control space lasers, operating them would presumably be cool according to at least some elders.

"Oh, you have an orbital space laser too? Any connection with the Yoder space lasers? My second cousin 3x removed's mother was a Yoder..."
