Okay, I take that back; most of them are so nuanced that (when you parse them) they make no sense.
Take the issue of the term: "Semi-automatic weapon".
According to many sources, that defines a firearm which will fire one shot with every pull of the trigger.
Imbeciles of the World, Unite!
I may or may not own a double-action revolver.
It will fire one shot with every pull of the trigger.
According to the lame-ass definitions provided by imbeciles who know nothing about firearms, that should be considered a "Semi-automatic firearm", and subject to draconian restrictions. But it's a Revolver, and not easy to reload, so they ignore this inconvenient fact item.
There are definitions on the internet which attempt to address this conundrum:
A semi-automatic firearm, or self-loading firearm, is one that not only fires a bullet each time the trigger is pulled, but also performs all steps necessary to prepare it to discharge again—assuming cartridges remain in the firearm's feed device. Typically, this includes extracting and ejecting the spent cartridge case from the firing chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber. To fire again, the trigger is released and re-pressed."Typically":
Well, what if you don't have to physically extract the "spent cartridge case", and what if the action of "recocking the firing mechanism and loading a new cartridge in the firing chamber" is accomplished by merely pulling the trigger again? How is this different?
A better, and more accurate definition of "semi-automatic" might be that you fire a shot each time the trigger is pulled until you run out of ammunition or discontinue pulling the trigger. That presupposes that you don't have to perform any manual action other than pulling the trigger again to fire the next shot.
Well, then you have just defined a double-action revolver .. against which the cognoscenti have no defense. Their definition requires that the gun "automatically" load the next round, instead of the user doing so "automatically" upon pulling the trigger again. (Petty bastards)
But gun-grabbers are all about restricting Second Amendment rights of people who use pistols ... rather than revolvers .. to perform the same function: pull the trigger to fire the next shot until the ammunition supply is exhausted. They're good with that. They are comfortable in their ignorance, believing that nobody can run a revolver and reload it as quickly as they (personally) might be expected to run a semi-automatic pistols, reloading from magazines.
I have just two things to say:
