Some folk, even progressive folk, have fired a gun and miraculously avoided murdering someone when they did.
Progressive or not, I'm happy to report a 100% avoidance rate.
Perhaps the meme that "guns are designed for murdering humans" doesn't resonate with anyone who's actually fired a gun and not murdered a human.
I believe the first guns fired spears, and later on they were made to fire bits of metal, or shrapnel. So I think they were originally meant for killing things, if not people. If guns were merely designed with no other functionality than to fire a projectile, then today we'd be dealing with little more than fireworks.
