So when an asteroid hurtles towards Earth I wouldn't be too surprised if the following classification is used by libertarians:
"Mild" Asteroid = 1 million dead
"Moderate" Asteroid = 1 billion dead
"Severe" Asteroid = Extinction level event (Oh well!)
If a humanity ending asteroid was discovered on a trajectory hurtling towards Earth, I can guarantee the batshit crazy "we must live alongside the asteroid" crowd would be out there advocating against government intervention to save the planet!
