I have no problem with refering to firearms as weapons. I think dodging the term makes it appear like gun owners are ashamed that their fireARMS are indeed weapons and are trying to obfuscate that fact.
I don't think anyone is buying that line and don't think it does us any favors.
I was taught at a young age that a firearm could be a dangerous weapon and as such demanded a great respect in handling. I can't think of any other tool that is as potentially dangerous to the user and bystanders aside maybe table saws - but the range on them isn't so great.
