If power decided to take your guns, or everybody's guns, they would have them. You have to know this. Armed private citizens pose absolutely no threat to national power. NONE. 

It's a simple question of how much firepower and how many fighters could be mustered at the point of contact.

It's dangerous to think of gun owning as a political act, as an assertion of political power. The days are long gone when rude farmers could fire shots heard around the world with smoothbore muskets.
