I'm just going to use dumb comparisons then. Who knows, maybe one will stick.
A paintbrush is used for painting. That doesn't mean you can't stick it up your butt for a good time.
To quote the brilliant, yet over-looked works of Sesame Street:
"One of these things is not like the others."
Perhaps you should compare a firearm to another equally patriotic symbol/object instead of trying to compare two completely unrelatable things.
Like a firework! Fireworks are awesome! And they explode into pretty colors!
