Okay. Most people seem to think they'd walk away from Omelas.
How about the Omelas in front of us? Why haven't we all walked away from this?
Not to call us hypocrites, but... We are hypocrites, and that's okay. Perhaps walking away asks so much of us that it's a losing strategy just because of how difficult it is. Perhaps reformation, with all its ability to be co-opted is still a better strategy because it's one people can get behind.
