I don't want to be too blunt, but this is the "uninformed" I was talking about. The same asymmetry was present in Vietnam, Iraq, and Afghanistan. The ability to level cities is not actually that helpful when the goal is to control the population. Modern revolutions don't involve standing armies that you can kill will tanks.
> outright revolution (at which point the constitution doesn't really matter)
It doesn't matter beyond the point of revolution. It matters a lot that it was in effect before the revolution.
> what can't be argued is that the 2nd amendment has been effective at protecting our rights. Our rights are routinely violated.
I'm not sure if you just don't understand the concept of a last resort or if you actually think that we're at the point of last resort already, in which case my only question is: Do you own a gun yet?
