I am not sure whether you are trying to be funny or if you are just being ironic and condescending. I'm hoping for the first option. No, I don't think we are all killers. But I do consider kendo and iaido to be lethal arts since we learn techniques that can kill a human being quite easily. I mean, I can kill you with a spoon, but I think a sword might do it a bit more efficiently, if you know what i mean. As I said in my previous post... just because we learn something that has a potential lethality doesn't mean we all become killers. It would be nice if someone who doesn't think kendo/iaido are "lethal arts" could explain why they think so.
