My mom used to ban toy guns in our house while I was growing up. For a little while during my childhood, I thought she was a bit prudish as other neighborhood kids seemed to have lots of fun playing shoot em up. I would have to go to the neighbors to play with gun toys. What seemed prudish, back then seems quite sensible now, looking back. Toy guns can look too real, from a distance. That's one of the many problems with toy gun play. What seemed a bit prudish, or out of step with the norm back then makes more sense now. My mom had good insight.
