Gun deaths in general are awful

Gun deaths from children is even worse.

But instead of talking about what you're doing to advocate for safer gun laws, or what trainings you take, what safety precautions to use, which guns have lower pressure points, proper techniques, conflict deescalation, what gun locks/safes you use or the myriad of other items that you could be communicating to show your concern for gun safety ... you want sympathy for life choices. You want pity.

If a child dies by a gun from your adult house, that's on you. It shouldn't be accessible to them. Why you feel the need to present your gun on facebook, that's a personal choice, and that personal choice is also saying "this item is accessible to you via me."
