No attempt at diversion at all, bro. I was just taking your words to their own (il)logical conclusion. Once again, words mean things; and if you didn't mean what you said, you should've said what you meant.
Sandy, you keep on saying that it's possible for a person to go into any gun shop and easily buy a conversion kit to modify a semi-automatic rifle to full automatic. Until this morning I honestly did not know if your assertion was correct, or if it was just something you pulled out of thin air; so I decided to find out. On my way to McDonald's this morning for my Egg McMuffin, I drove past the local gun shop where I purchased my own pistol, and stopped in to ask one of the owners if what you said is true. When I asked him, he laughed. Literally. (There were also some eye-rolls involved.) He said that it's just as illegal to modify a firearm to full auto as it is to buy or sell an automatic weapon, and that no licensed gun dealer can or will sell any sort of hardware to facilitate that process. Sandy, if you have to resort to making stuff up to bolster your argument, that means that your argument is unsustainable by real facts.
I will also say that this lively conversation we've had over the past couple of days has had an unintended consequence. Specifically, it has underscored for me the fact that there are people who want to determine gun policy who (1) are abysmally ignorant of firearms and how they work, and also of current gun laws, and (2) have shown themselves willing to use distortion, half-truth, and outright falsehood in order to restrict gun ownership. And as a gun-owner myself, that is something I cannot abide, and also the kind of thing that the NRA tries to prevent from happening. So although I have not been an NRA member, this morning I went to their website and joined up. (Only a one-year membership though, at least for the time being--but even at that membership level I get a nifty duffel bag out of the deal, so that's kinda cool.) So thank you, Sandy, for helping me see the light.
