That does seem a pretty pointed thing you could've got from the old Wildstorm imprint (or Ultimates if it'd been a bit less, uh, Ultimates)The funny thing is, I can actually picture a modern version still playing very straight with the idea of superheroes needing a square-jawed, white, classically 50s man to be the front man to be accepted. It's just it'd be an explicit commentary on society and someone like John Stewart would make a pointed comment about it.
The Amish thing always annoyed me. It seemed so silly and Deus Ex Machina.
JSA Liberty Files had a similar bait and switch but... well it was a lot more effective cause of just how terrifying the idea of Nazi Superman was."He's not done anything because he's Amish" is a pretty weird explanation of where he's been. On latest reading, the talk of the powerful super-strong alien seems a planned "is SUPERMAN the threat?" red herring before we're tricked into thinking it's Starro.
