I find the concept of the left of returning to a primitive existance so laughable...the reality is that if (when) this should happen, the environmental wack jobs would be the first to whine for someone to provide them with food, water, shelter, safety.
The “let’s live as one with the earth” idiots would be the first to die off, while we Redneck-types living in rural America would do very well. Oh the Irony!
They are also the same ones who want everyone concentrated in urban rabbit hutches, dependent on public transportation and government for their existence, and thus easily controlled.
