While I disagree with Travis' idea of that sort of protest, I don't see this as an issue of weapon possession. I think schools are way too cautious with this sort of thing, just the mere mention of a gun sets them off. There are better signs of kids who are mentally unstable and need attention than talking about guns. There are also better ways to handle it than giving them an 'F' or suspending them.Some people do a lot to defend the right of weapon possession I am afraid.
I pretended to play Star Wars and had Duck Hunt on Nintendo when I was in elementary school and it didn't harm me mentally. Like Perun, my parents just told me that shooting people isn't OK and war is not fun and games.
