I laugh at this as well. Most of today's gun owners clutch their weapons as a bastion against attempts for their liberty, while simultaneously crying that for decades the government has done nothing but just that!

Sure the OP scenario of sudden-dictator is bizarre, that's not how it works. If the U.S. ever falls to dictatorship, it will be like a frog boiling in water, and there will never be a single trigger point to erupt the populace into violent revolt.

Just look at what we have today! The majority of gun owners are the staunchest supporters of our most authoritarian president ever. You don't need to worry about a violent revolution when the gun owners are "voting" for you already.
