Don’t demonize guns.
BTTT
Don’t treat a toy gun as a real gun. Don’t leave your children confused between the two by pretending a toy is real. It takes away respect for the real guns.
You use the toy guns as a teaching tool. You explain how to handle a real gun using the toy gun. There are lots of teaching aids that are not the real thing even in the adult world. A child will not be confused between a toy gun with a red tip and a real gun. You train them.
