Nah, Joe, you did not speak too soon. But while we are having a serious discussion, most of us are adult enough to throw a little humor in too. And most of us recognize which parts are joking and which are serious.
See, I know he is joking about using his left thumb only. He is right-handed. I might have believed him if he had said his right thumb, but we don't call it weak handed shooting for no reason.
And on the serious side, it looks like 03LighteningRocks and I are actually agreeing, but putting it differently. It is not the carrying of the gun that would make the child nervous, but the actions (wired up, or acting as if there is imminent danger at all times) might. Walking around with confidence, whether armed or not, just teaches the child to be confident.
The only real question seems to be a difference of opinion on how we act when we are carrying in the home. Some outside visitors might see this as being jumpy and nervous while others might see it as being comfortable and confident. And no one can tell how the kids will see it unless they ask and it is explained to them. And then the explanation can make a big difference, as per his example.
That example could also be changed to:
"Why does Daddy wear a gun around the house?"
"Daddy is a police man. He just got off from work."
"Why does Joey's daddy wear a gun around the house?"
"Because Joey's daddy is likes to have a gun in case he needs it to protect his family in case Daddy can't get there in time."
Now the kid would learn a completely different lesson, based solely on who explains the behavior he is seeing.
