The diary "The Stunning Ignorance of Kossacks About Guns" is false advertising. The title has no relationship to the text, which is overwhelmingly truthful--but irrelevant--information. In fact, this diary is designed to advance three fantasies of pro-gun advocates.
First, that diary provides a long history of antique guns. Lovely, but almost entirely irrelevant. Is there any reader on this site who is unaware that today's guns are dramatically different than the "arms" mentioned in the Second Amendment? I don't think so. There's no "ignorance" here that's relevant to the gun violence debate.
Here's what's relevant. In federal law, all those Revolutionary War-era guns, as well as authentic copies of those guns, are EXCLUDED from the definition of "firearms." See 18 USC 921(a)(3) and (a)(16). So all the gun violence protection laws we're talking about on this website--assault weapon bans, restrictions on ammunition magazines, universal background checks, and the rest--do not apply to the guns that the Founding Fathers talked about.
Second, that diary implies that a misunderstanding of the word "semiautomatic" is important to the advocates of gun restrictions. Yes, some people say "semiautomatic" when they mean to say "semiautomatic assault weapon," but does it really matter at all? Everybody on this site understands that they're supporting reapplication and strengthening of the 1994 federal assault weapons ban. That law clearly distinguished between semiautomatic assault weapons and conventional semiautomatic guns. Senator Dianne Feinstein even went so far as to attach a very long list of guns that were not subject to the ban, quite an unusual step.
Third, that diary suggests that proponents of an assault weapons ban misuse the term "assault rifles." That diary claims that "assault rifles" refers to military weapons that are capable of fully automatic fire. This is a standard NRA argument. It was the gun industry that started calling their semiautomatic copies of military weapons "assault rifles" and "assault weapons." Advocates of an assault weapons ban are simply using industry-created language. And let's be clear--everybody knows what we're talking about. There is no "ignorance."
