I disagree. I can understand resisting it to a degree, but how would they "rise up"?
It will be known very soon what public officials support such a ban. Their homes would likely have the windows removed by a 22 rimfire at a distance or be a smoldering ruin.
Cells of individuals would form. This would be very different than gangs. Gangs rat each other out to the cops. Cells of individuals would have no such motivation.
The military will be deployed to try and protect these people and their homes. Some attacks will continue, many will poke and prod where they can. Unlike the insurgents in Iraq, people in the US would focus on materiel more than a body count. A 22 round through the sidewall of a $100 tire and a $300 window is going to drain resources for the government.
Infrastructure would be targeted. Getting back to the lowly 22. With a homemade 22 suppressor, a proper vehicle, and some planning you can take out whole sections of a city's power grid. A shovel and a map will take care of telecommunications cables.
The reaction of people who are not fighting the government will be mixed. Some will provide support for those who are fighting, not because of the gun issue, but because of other grievances they have with the government. Others because they see those fighting as the winning side.
Others will side with the government, but risk being targeted by those who are fighting the government. Those who do support the government will likely find that the government will provide little in terms of protection or resources in return for their loyalty.
