The government wouldn't be so gentle? You mean they would kill me, my family, and my friends TWICE? Virtually everyone at Waco died.
When the time comes, the action will look more like the DC snipers, but multiplied by many hundreds and targetting those who continue to represent the illegitimate central government.
One primary target during the Revolution was those who chose to collect fees and taxes or those who were prepared to exercise force on behalf of the authorities. Postal service, Forest Service, National Park Service, police services... all of these are the people who will have to take sides. Such a revolution is not something that any of us should wish for, but do not doubt that there will be those who choose freedom over chains.
You'll be branded terrorists and you'll get caught and executed. The IRA did the same thing once and they got caught, too. They had the advantage of living in areas that were sympathetic to their cause.
Guns won't ever be totally outlawed in the U.S. You may see liberal wet dreams like required gun registrations and such-- but those would be tolerated by the general public and the public would rat armed resistance out at every opportunity if the cause was gun registrations.
There's a difference between supporting something like "general RTKBA" and having people allow militia groups to terrorize people by sniping out of cars-- even if those people are just politicians. The mass public would not support that and would actively act against you.
You couldn't keep your activities secret enough to pull it off.
