From Open Source Defense:

So if your spouse is uncomfortable having a gun in the house, they probably just haven’t been exposed to guns in any context other than a violent news story or someone getting killed in a movie. If 100% of the times you’d seen a gun involved someone getting murdered, you’d be worried too.

The solution is to familiarize them. But someone’s first gun experience is high variance. A great experience can convert them, and a bad experience can turn them off for life. So how do you make sure it’s great?
