If we ever have to take on the prohibitionists in combat, reducing their strength by two would require inflicting two casualties. Or, if the foes in question are support personnel, two civilian casualties. That’s not something our side would do willingly.
As an alternative, we can try to change the score by two in a nicer way. Teach freedom — including self-defense skills. Each person educated away from the totalitarian side is a loss for them and a win for us — and nobody has to die.
Thus my daughter is a “gun nut.”
