A gun is just a tool. That family looks scary because the tool they love has only one purpose... To kill. If you're bad at it you can scare or mame. To not be bad at it you have to practice.

But imagine the same picture with the family holding butchering knives, or hammers, or a drill or a broom or guitars. Any of those objects are fine. But the message really changes when everyone is holding the tool like they're ready to use it. I use my mind a lot. In my family pictures we hold up our minds.
