It all comes down to this: Our guns would ensure the Military has a say.
As long as we have guns, even just handguns with 5 bullets in the clip, we'll fight when the next emperor palpatine becomes the POTUS and does away with congress and the ballot box. (If not sooner.)
At this point, the US military, his enforcers, will be told to go and kill their friends and families, who are resisting his will. As brainwashed as they are, they will still face a serious moral dillemma... And the military would be split if not fully siding with us.
If we didn't have the guns though, we couldn't fight at all, and the military wouldn't be needed to go out and stop us.
The trouble is it will happen slowly. You send the men to different distracts to enforce control. When you "arrest" men 1 at a time, people will consider the victim as an extremists or a nut job. It will be no different than it was when neighbors, and brothers turned people in as "communists" 1 person at a time.
