Really? Where I went to high school 35 years ago, nearly every boy and a few girls, including myself, owned at least one gun. Boys with vehicles kept rifles or shotguns in the trunk or in a rack in the back window of a pickup. They went hunting and target shooting after school quite often. Nobody locked their vehicles, and nobody would even consider taking or even touching somebody else's guns.
There were no "school shootings." Boys would have fist fights once in a great while, but nobody ever pulled out a gun to make a finer point. Guns were respected tools, nothing more. What's changed is our culture. When you live in a culture where it's okay to kill an unborn child because it is inconvenient right up until it's ready to be delivered, and you can dispose of it by stabbing the base of its skull with a scissors and then collapse its head by sucking out its brain with a vacuum, it isn't surprising that there are more shooting deaths. When you live in a culture that celebrates death through entertainment venues, it's not surprising that there are more shooting deaths. Listened to any rap songs lately? When you live ina culture where parents blame everyone but their own kid for that kid's bad behavior and exercise no discipline whatsoever, is it surprising that that kid feels he can do whatever to whomever whenever he feels like it? When you live in a culture where the education system teaches that anything anyone does is okay and is morally equivalent to an accepted, established behavior, is it surprising that confused youths feel justified in taking the life of another?
