Freedom of the press and freedom of speech are what prevent the government from having complete and total dominance over all digital and analogue communications as well as public perception.You can't organize a resistance even with the First Amendment. It would be treason to do so. You are going to have a real hard time explaining how organizing a plan to overthrow the govt would be covered by the 1st Amendment.
Without the first amendment there is nothing stopping them from controlling the internet and without the internet a resistance would fail against a government that can still communicate coast-to-coast instantly.
Without the first amendment there is nothing stopping them from controlling the public's opinion of our little resistance movement.
And those guys are communicating with each other. If they weren't able to use technology to communicate they wouldn't be nearly as effective.And if ever comes down to violent revolution, you won't need guns anyway. Look at how insurgents are fighting US soldiers in Iraq. That's how the next revolution would be fought. Home made bombs, roadside IEDs, etc.
You can't go toe to toe with US Army and expect to survive.
