Guns have been restricted before, during and after the drafting of the BoR. Everyone knows that the language of 2A doesn't apply to prisoners and never did, but no one in the "shall not be infringed" camp can explain that. Instead they cling to a fantasy that never existed, and that's why they are extremists who are out of touch with reality, fighting a war they lost two centuries ago.
Just an FYI, the 'prisoners' strawman is a dead giveaway --that's boilerplate talking points I've seen many other places. It made no sense then because the RKBA and other rights were removed with Due Process in accordance with other amendments as intended, it makes no sense when you say it. Even still, there's lots of contradictions between the law as we aspire to abide by it and the law as it is; case in point the Japanese Internment mentioned, as well as the notorious selective enforcement of gun laws in Jim Crow or other areas even after the 14th Amendment (or even before it, for that matter). Just because an injustice persists long enough, even from the starting point, does not make it transmute into justice after enough time. We have more than enough precedent in western human history to uphold the Defense of Marriage Act if that were the case
Have I explained it to your liking?
Almost no one even understands what gun control is, let alone how to fight it.
Another tell. Gun owners, who you know, actually have to abide by this insane minefield of rules and regulations to stay out of the pin, are extremely aware of 'what gun control is,' and how illogical & baseless & poorly written the vast majority is. I've found one of the most effective methods to sway the ignorant or 'undecided' to start down our path is to tell them the truth about the gun laws the anti's have erected; exactly what they say you must do to remain free. Nonsensical rules on silencers, barrel lengths, forward grips, cross-state transfers, bore sizes, foreign made parts, bans on meaningless features, ignorant bans on hollowpoints as being 'armor piercing,' bans on armor piercing ammo that aren't based on the ability to pierce armor --the list is a long, and very stupid one. If I can hold a person's interest long enough (usually can if I sprinkle it out over a range trip) they are sincerely questioning gun laws by the end of the day. Stuff about the Founders and Federalist papers can come later, lots later; the brass tacks of gun control are enough to sour anyone's appetite.
Instead they cling to a fantasy that never existed, and that's why they are extremists who are out of touch with reality, fighting a war they lost two centuries ago.
The fantasy where guns needed no serial numbers, had no registration, could be mailed over economical modes of transport, could be carried on or about one's person in public (usually openly), had no restriction on length, bore diameter, or the ability to fire automatically, and required no license to manufacture or market. That fantasy persisted for the first 158 years of our nation (not counting the decades if not centuries before the Revolution). All that mattered was whether you were reckless or hurt people with your guns (or whether you hid them on your person as this was assumed to be for unsavory purposes). Rules on powder storage existed because of the physical realities of black powder in an era of oil lamps and densely packed wood structures; not political whims.
In fact, it was a crack down on imported Brown Bess muskets issued to the British Regulars that led to a boom in domestic manufacture of rifled muskets for militia, a crackdown on powder specifically sparked the firefight that began the revolution.
Your "two centuries" crack is, I assume, another ignorant assumption about the Civil War. The fact is, federal gun control did not exist until the turn of the 20th century, and was relegated to enclaves of poorly or unrepresented minorities in the areas it did exist on a local level. Gun Control is the aberration, that had no place in our system as originally designed, and only came into being as part of progressive reforms along with such beauties as eugenics & forced sterilization, insane asylums & lobotomy, 'reformative' prisons where rape is used as a tool for penance, and Alcohol Prohibition, the very spit of "seemed like a good idea at the time."
Look up Big Tim Sullivan to see what kind of heroes paved the way for future gun control holy rollers. A more disgusting human being has never existed.
