Idont really understand the question
As a Kid I didn’t know much about guns. I knew they existed, Police officers dont exactly hide them. My PArsha coloring book had Eisav, Paroh etc carrying guns.
As far as I was concerned they werent for yidden, I wasnt allowed to even play with water gun or cap guns on Purim, but I knew they existed.

It is 100% your call what to hang up in your home
