So my moderate Democrat step uncle (who was apolitical) isn’t dead? So he doesn’t have the problem of being…well, dead? Where did he go Link? Is he on vacation? Is he in New Orleans for the Super Bowl and Mardi Gras? Visiting Central Park in New York? Perhaps at a bluegrass festival in Live Oak? Please enlighten me on why average people are never murdered, because that’s basically what you just said.
No one is glad your step uncle died, and no one thinks his death is any less meaningful because of his political leanings (or lack thereof). That said, there's no guarantee that he'd have lived had be been armed. Just as there's no guarantee that the monsters who shot and killed him would have had the means had they not lived in America, a country that allows even the most hardened lawbreaker the opportunity to gain access to military-grade weaponry so long as he's willing to travel to the right state and dealer.
His point is that
average people are almost never murdered, which is, to be fair, absolutely true. In 2009, the murder rate dropped to 5 per 100,000, the lowest it's ever been. (That murder rate includes "non-negligent manslaughter.")
Still pretty high? Arguably. But if your uncle is white, then his likelihood to have been murdered drops even more. In New York City, for example, 96% of shooting victims are either black or latino. African Americans make up about 12% of the population, but account for over 50% of the shooting victims nationally. And since your uncle was in his home, it's also relevant to mention that if you're going to be shot and killed by a stranger, it's unlikely to happen in your own home -- only 4.8% of murders are committed there.
No one is glad your uncle died -- he got dealt a really ugly hand in the sh**ttiest lottery known to man. Sorry. But those of us who think there needs to be more regulations on gun ownership are motivated in taking guns out of the hands of the bad guys -- something the NRA is literally on the record of being against everywhere but in press releases.
