It is a chemical and it is used as a weapon, but according to you it is not a chemical weapon. If lead was being somehow weaponized and dropped on human beings by the military with deadly effects it too would classify as a chemical weapon. I have contempt for abject stupidity, and in an ideal world would never have to interact with anyone like you, but the world is far from ideal.
