Because people are ignorant. They have not been taught and, more importantly, they have not learned.
Man is an undisciplined monkey with no inherent sense of order or "common sense". He must be taught.
As well, very few people as a percentage of the general population have been shot. Many have injured themselves with knives. Thus, people are terrified of knives, but have no idea how destructive gunfire is.
Ask any INGOer cop how many times they have had people curse or make obscene gestures when they have guns pointed at them. I was teaching the legal portion of a class at Wildcat Valley. I watched the class wave guns about like cheerleaders with pom-poms on the range. However, as I was waiting for my time, I opened my folding knife to cut open a tangelo. The knife made an audible click (Spyderco Endura II SS). Every. Single. Person in the class turned to look at the knife and some made audible monkey hoots.
Why were they waving guns around like pom poms but all expressed concern over a knife being opened behind them? Because they had all been cut by a knife (usually their own in the kitchen over a bagel), but few of them had shot themselves or seen others shot.
Why do they treat guns like things other than guns? Because they don't know any better. That is why the safety rules are so important. They give order out of chaos. They make undisciplined hooting monkeys that points guns at themselves into men handling dangerous machinery.
Some people just get too comfortable and being simple minded creatures will be the cause of their own destruction.
