Based on Umberto Eco's list for recognizing facism, "The enemy is both weak and strong.", Schrodinger's Nightmare is where the enemy is both your worst nightmare and just a dream that can easily be controlled and eliminated, depending on whether the rhetoric wants the population to be considered awake and alert to the problems, or asleep and caught unaware.
The enemy exists in an undefined nightmare state, where they could present a mortal danger or could be weak and ineffective, depending on which one is desired for the rhetoric. Though people or groups can have both strengths and weaknesses, Schrodinger's Nightmare rhetoric is not interested in what those strengths and weaknesses are, or anything factual for that matter; instead, it invents extremes for terrorizing the population, to drive fear and hatred into them.
Awake and alert: "So we have these carrot-eaters, who want carrots to be the only food. Obviously no one can survive only on carrots. I think natural selection will sort out these weaklings pretty quick."
Asleep and caught unaware: "Carrot-eaters swarmed a grocery store in the early morning hours, when parents were taking their kids to school, overwhelming the grocery staff with their 'carrots only' picket signs and disrupting a mother who was trying to get some quick breakfast for her kid, the pair already running late to get to school."
"With it made clear the lengths these carrots-only freaks will go to in their crusade, it's clear we're living in a real Schrodinger's Nightmare. When are people going to wake up and do something? They're destroying everything. And remember, they are weak, they aren't getting the right nutrition. It won't be challenging to take them out."
