There is a very strict rule when dealing with firearms. You NEVER EVER point a gun at anyone else. Ever. No joking. No kidding around. You only point a gun at someone if you are prepared to imminently use it against that person. This means, literally, "life or death".
I've been handling guns for over 45 years and I've never even considered breaking that rule, nor have I seen anyone else break it. BTW one corollary to this is "there is no such thing as an accidental discharge, only a negligent discharge".
Heck, I've even "died" in paintball enough times to know that I don't like the odds.
Software, even malicious software, is OTOH "meh". Even if it's written by government hackers. It's simply not scary at all. IMO the analogy of guns to software was probably written by someone who wasn't familiar with firearms.
And you're right about my abhorrence of Windows. For close to twenty years now, everyone has sat around and said "oh no, woe is me, another virus, it's hopeless, it's terrible, I'm scared, my business is threatened, hackers are stealing my secrets". The details change, the general story is the same.
To which my response is: "the only winning move is not to play". So why do people keep using Windows?
And surely the most popular OS will be the one most targeted by criminals no matter what it is.
My heart starts racing a bit when I suspect my systems might be tampered with, so I think the metaphor does apply. What would have been better if the parent provided a better, less hyperbolic metaphor.
