As to one of the stupid arguments the anti-rights people have come up with,

There’s no historical evidence to suggest that the Second Amendment was “created to ensure Southern slaveowners the right to maintain & arm slave patrols to put down insurrections amongst the enslaved,” even if southerners subsequently used guns for their nefarious purposes. …The right to self-defense, in fact, is incompatible with the idea of slavery — it runs counter to the arguments made by the Founders, even if some of them were hypocrites… The animating ideas of the Second Amendment — both as personal and communal protection — are predicated on natural rights and English common law. And while nearly every intellectual, political, and military leader of the Founding generation stressed the importance of the right to bear arms as a means of preserving liberty, some of its most vociferous champions were against slavery. …The first American effort to codify and guarantee the right to bear arms was made in Pennsylvania, under a conference run by Benjamin Franklin, also president of the colony’s anti–slavery society. The second colony to do so was Vermont, where there were few slaves and no fear of a revolt. …What’s most ironic about Jones, who names herself after 19th-century civil-rights leader Ida B. Wells, is that the historic figure was a champion of the Second Amendment. She maintained…“that a Winchester rifle should have a place of honor in every black home, and it should be used for that protection which the law refuses to give.”
