No freedom has ever been won or guarded with the types of firearms legal under the 2nd amendment.
Ever. Anywhere.
Literally every single example you're going to reply with is wrong.
Not even the American Revolution was "won" using personally-owned weapons. It was won using artillery, naval vessels, mercenaries from overseas, and the first thing that happened when a patriot showed up for his patriotic duty with his pappy's musket was throw it in the trash and issue a soldier a Brown Bess or Committee of Safety musket so that the caliber, rate of fire, effective range, and operating procedures were the same amongst all soldiers.
Not in Vietnam, not in Afghanistan, not anywhere at any time has a conflict against a government either foreign or domestic been defeated using personally-owned weapons.
The few times in America where it was tried, post Revolutionary War, the tax/whiskey/voting rights rebellioneers were crushed under the might of a pathetically small standing army that used cavalry and artillery to intimidate them.
The various slave rebellions and civil rights conflicts changed nothing. Lawyers, peaceful protest, not-so-peaceful-protest, and public opinion changed things.
In terms of ethnic violence, everywhere, every time, in each and every case where a smaller population has armed itself to protect itself the only result has been the employment of mechanized terror against them with horrific results.
"Oh but the Warsaw Ghetto.." nope. The germans went in, received fire from personal weapons, left and leveled the ghetto with tanks and mortars.
"Oh but if the Tutsis had had rif.." nope. Both sides had rifles. When the Tutsis started scrouging AKs, the Hutus responded with grenades, automatic weapons, and bulldozers. The government didn't even do most of the killing, instead ordering the Hutu majority population to do it for them, at the point of a belt-fed machine gun. During the Kibeho massacre guns were too slow so they just mortared the sea of refugees with 60mm mortars. If every single Tutsi had possessed an automatic rifle with infinite ammunition, they would have all still been murdered. A rifle is useless against 60mm mortars and air-mobile military forces.
The only protection against tyranny is strong civic organizations and the rule of law. When those break down whoever has the most cash to buy the most heavy weapons, usually the government, wins.
The only thing the wide availability of weapons has done in areas WITHOUT strong civic organizations and the rule of law has been to turn vast swathes of Pakistan and Afghanistan into lawless zones of chaos and misery, ruled by whichever warlord can get the most RPGs or convince their followers to become suicide bombers.
Ten million personal AR-15s are useless against ten thousand mechanized infantrymen.
Firearms protecting rights is a myth.
