My views on what RKBA means are colored by what I grew up with: it began with my dad teaching me safe gun handling in 1954 and me going hunting with Uncle Ed and his dog Henry, and included respect for Rob Williams for standing against the KKK in Monroe County NC.
The Tennessee Constitution, Article I Rights of the Citizen, Section 26 Right to Keep and Bear Arms, states the citizens have the right to keep and bear arms and the legislature has the power to regulate arms use in public with a view to prevent crime. By court rulings, attorney general opinions, and statements of legislative intent, regulation must affect criminal use without unduly restricting lawful, traditional ownership and use of arms (including hunting, self-defense against attack by human or animal, protecting livestock from predators, civilian marksmanship training prepatory to military service, collection as curio or ornament). Apparently lawful use included the rebellion by the GI NonPartisan League at Athens, Aug 1946.

Either we support all lawful traditional uses of arms, or we lose those rights one by one, people. No picking where RKBA begins or ends and no limiting to one or the other. Our opposition sees the Heller and McDonald decisions ((a) the right of the people is an individual right and (b) prohibition is not reasonable regulation) as wrongly decided and want to overturn them ((a) no right to bear arms for you and (b) bans are OK with us). They want either to repeal the Second Amendment (Rep. Major Owns, Alan Dershowitz, et al.) or to admend it to "the right of the people to keep and bear Arms
when serving in the Militia shall not be infringed" (Justice John Paul Stevens).
Ultimately, the choice is between the constitution of Jefferson and Madison, government of the people by the people for the people protected by volunteers raised from the people, or the living constitution evolving into Hobbes and Webber, absolute state justified by monopoly on force, government of the people by the government for the government protected by forces loyal to the government against the people.
The soap box is working.
The ballot box will work if you bother to vote.
The bullet box is for the gravest extreme and we're not there, so please no more. But as I recall it was liberal skeptics who researched and discovered that the founders intended RKBA as a guard against tyranny.
