north of 60, i'm glad you choose to kill your own food instead of supporting factory farming. since that is the way you're raising your children, it makes sense to teach them that guns are acceptable tools for adult use. since my son is vegan and we don't support killing of any kind (not even mosquitoes), almost zero exposure (thus far; he's only 4) just makes more sense for us, y'know?
hmmm... others have asked about how to "shoot down" the interest (sorry, i had to) when it arises. i just treat it like anything else. i say "baby, no blasting" or "sweetheart, we don't kill people" in the same tone of voice i use for "cas, sharpies are for paper only". we've certainly had deeper conversations about it, but i try to keep it towards how *i* feel about guns, war, meat, et cetera without using too much "you can't do xyz" language. the gentle reminders are issued along with the rest of what we try to (as subtly as possible) teach him daily, as the need presents itself. i don't think he feels ashamed, because i do my best to not preach, so hopefully he'll have less reason to want to rebel in the future.
mostly, like i said, talking about my own truest feelings about a subject impacts him the most. anyway, i think it does because that's certainly when *i* feel most connected with him. lately, especially because his empathy and logic are both much more developed than even a yr ago, i've been reaching out like this more and more. if my parents had really bothered to show me how passionate they were about the reason behind a rule, instead of just yelling and being punitive, it would have made so much more sense. it's been hard to get to a place like this; like i said, his aging has helped enormously. arenas like this are so helpful, though, because we can sort out those deep feelings here, and get affected by other POVs too, as a sort of practice for when we share those feelings with the kids.
peace and goodwill to you all. whether your beliefs are similar to mine or not, practice them strongly and with all your heart. that is the best example your kids can see.
