I’m eagerly waiting to watch the “Consuming of the poop” stage when they are all starving in the dark after their collapse hits. They can’t farm, build anything as simple as a cooking fire or hunt. So it should be entertaining to see.
Then when they run to the feral enclaves after they are barred from ours, we can enjoy the final Festivus celebration...”The bleeding on the ground” ritual.
And we can take pride in our tolerance for accepting the customs of other faiths.
So, you're saying they'd have to burn down a building in order to cook their "dirt" sammiches.
