I haven't read the entire thread, but it seems very similar to what my kids go through. They have their own firearms, and hunt and shoot right beside me. Of course, all kids talk about the things they like so I (or my wife while I am away) get plenty of calls from the school. They never talk about their use as "weapons" only as a hobby, sport, and just something they did over the weekend.
At first I tried the polite tact. Living in a rural area I thought all I would need was let the school know that my daughters do shoot and like it. I let them know that should my daughters ever use language indicating violence toward another I want to know as I would back them and add to the punishment at home. However, I have never heard such from them and neither did the teachers.
I was also firm on the point that I defend a free country that protects the right to speak ones mind and of ones hobbies too. I will not tell my children not to speak of the hunt we had, or our day at the range, or even how they did on a 3-D course (yes, even bows caused these calls). They can speak of them the same as another child might tell of the drag races their dad took them too, or the football game they played.
I could go through a long list of the types of calls I got and it kinda got ridiculous. Ask my younger daughter what she got for birthday and send her to the office for the honest answer (a rifle). Ask my oldest her favorite thing to do with her dad and a few minutes later I receive a call because "hunting is not an appropriate past time for a young girl."
My kids became the unwitting battle front front, not for the right to bear arms in my mind, but for the right to speak freely. Fortunately, my kids are very peaceful "turn the other cheek" type, but with stubborn streaks as wide as their mom's. They simply refused to give false answers to questions and avoid topics because of someone being offended. If their friends were talking about their weekends and they were involved then I would get a call. When they were asked for a favorite picture my oldest took in this one:
And of course I got call. For what? The blood? I would buy that since it is a graphic pic since we had no better she took it. Nope, because it showed the bow she used.
So far no action as been taken against my kids as far as punishment. Once they were about to when my oldest decided to tell them that "I love to shoot the way you love to teach. So I will talk about it just you talk about teaching when you aren't even here. Why is that a problem?" I actually put on my uniform for that one and asked them to explain why I should keep wearing it if my kids can't enjoy the same freedoms I protect for them.
Their usual point is that other kids might be frightened by it, so I said show me one. They could not. All the other kids thought it was the coolest and many of the boys offered up that their dads took them hunting too. So I asked again if my kids EVER use threatening language and no they don't. I let them know that that kind of talk is the only reason I would allow any punishment even if I must take them to court. Since Kala thinks hitting others is not "ladylike" and Kenzie thinks fighting is "for idiots." I doubt I'll ever have a problem. Especially with Kala being a star student in all other respects. Kenzie didn't get that gene I'm afraid, but is still one of the best behaved kids they have.
Ok rant over. I just think it insane how some things have changed.
