Some people here feel that voting means you grant consent
Kent Snyder hit the X ring on that in a footnote in Nation of Cowards.
To whit: some things are wrong, even if the majority votes it.
His example was a hypothetical, duly constructed democracy consisting of two men and a woman.
They lawfully created their democracy by mutual consent, and laid down fair rules in a founding document. Everything was fully kosher, as even the wisest among us would agree.
Some time later, in full accordance with Roberts Rules of Order, and in compliance with the founding document of their democracy, the majority voted that the men could have sex with the woman whenever they wanted, whether she wanted to or not, and specified that resistance to such advances would be unlawful.
Admitedly, the example is contrived, but it neatly illustrates the point.
You can't use majority rule to legalize rape, and there are some things that are placed beyond the bounds of such discourse.
The right of self defense, and the ability to use tools to effect that defense is one of them.
The other is that the only just government is "by the consent of the governed". If you accept that, then it follows that any and ALL power wielded by government is "on loan". Since the power is on loan, it can be taken back, and the 2nd amendment is ultimately about preserving the MEANS of recovering that power from tyrants who refuse to return it.
This implies that the use of force is both honorable and permissible under certain circumstances. The precise nature of those circumstances are open to debate, but Judge Kozinski, who dissented with the 9th circuit court on Silviera vs Locklear summed up some of them nicely:
My excellent colleagues have forgotten these bitter lessons of history. The prospect of tyranny may not grab the headlines the way vivid stories of gun crime routinely do. But few saw the Third Reich coming until it was too late. The Second Amendment is a doomsday provision, one designed for those exceptionally rare circumstances where all other rights have failed—where the government refuses to stand for reelection and silences those who protest; where courts have lost the courage to oppose, or can find no one to enforce their decrees. However improbable these contingencies may seem today, facing them unprepared is a mistake a free people get to make only once.
Other generally accepted reasons to use force are to prevent systematic mass* killings of innocents by government**, it's precursors, (typically mass relocation) and to protect the integrity of the vote. For information on this, search this forum for The Battle of Athens, Georgia in which WWII veterans used arms to prevent a corrupt sherrif's plan to ensure his own re-election by counting the votes himself, along with his cronies.
*This also applies to intentional killings of individuals by government as well. There are a couple of supreme court cases that upheld a criminal's right of self defense when ambushed by government. In these cases, the law officers simply opened fire without identifying themselves, or attempting to actually apprehend the suspect.
**Interestingly, the "Bonus Army", composed of veterans of WW I peacefully marched on DC and setup camp, seeking early payment of their bonuses during the Depression. Since their intentions were peaceful, they came unarmed. Eventually, they Army burned their camps, and attacked with cavalry and tanks. Many died.
