I agree that guns are fun, i have a few of them, just had to shoot a skunk a couple nights ago. When i lived in the city i had a BB pistol just for shooting targets in the back yard, now i've got a shotgun and a high power air rifle that takes care of most of the stuff i need around the farm. At 11:30 at night dropping that skunk with a silent shot to the head worked out pretty good. Definitely don't take any joy in killing 'pest' animals but it kept digging into the barn and fuckin' with the katz. I feel about the same about guns as I feel about chainsaws, they are powerful and dangerous, but also kinda fun and its nice to have nice ones.
What is fucked up is the fetishization of violence and killing. For a lot of gun fetishists, owning a gun is a power move, that is pretty anti-christian. Seems endemic of the generation raised on John Wayne and Clint Eastwood, idolization of killing and the notion that you can somehow 'kill for good' based on a fictionalized understanding of good and evil. My personal theory is that a lot of boomers spent a lot of time as kids watching TV - which was kind of a new thing- and people hadn't really evolved the bullshit filters or the psychological coping tools that later generations have developed.... also just generally weak minded people are disproportionately influenced by the media they consume, like school shooters that are already kinda misguided seeing a movie that glorifies shooting people and their brains can't distinguish the fact that its a really bad idea and fiction.
Jussayin' the guy that said 'the meek will inherit the earth' and 'turn the other cheek' doesn't want you owning 20 assault rifles and spending all your free time dreaming about how much fun it would be to go all Dirty Harry on someone who broke into your house. That's kinda like, the whole point of christianity. Its not so much about rules and punishment, its about embracing a spirit of benevolence and good will to others so your own life will be more fulfilling and you can be a positive influence in the world instead of spending all day in a dark room cleaning your guns and thinking all kinds of malicious fucked up thoughts while your brain rots from the inside.
