"A system for treating disease based on the administration of minute doses of a drug that in massive amounts produces symptoms in healthy individuals similar to those of the disease itself. "
I believe the bullet is supposed to be the minute dose and shooting all the fascists would count as administering the dose in massive amounts. They could also just be saying it’s a homebrew cure since most of my fellow Americans have guns and like to talk about them using them liberally.
Bless it’s heart it’s doing its best.
