It would indeed take divine intervention. That alone would save the mess liberalism has created through it’s ‘everything is acceptable” ethos. That aside, it’s Road Warrior, and yes, beyond.
The good part of that is that by far, most libs would die off because they are wholly unfit for the whole Darwinian “survival of the fittest” gospel they rally around. They can’t blame us for that. We on the right are far more suited, through our beliefs, morality and overall ‘who we are as people’ to survive the chaos they created.
I said on another thread RE this subject, many would starve outright once the food left in grocery stores ran out. Survivors would then be sold into slavery by their fellow libs, or become the literal slavemasters themselves. They would rapidly turn on each other regardless as they went feral. Most (though not all) of us share that problem. Throw in the disease, death from violence/rape/etc. and their anarchy solves itself with little help on our part.
Ultimately there will be far more of us left alive, organized and self sufficient, than them and there will be no ACLU to make us ‘feel’ bad about not wishing to repeat the mistakes of our past by embracing them. Perhaps then, we can start over as ‘America’.
