You're going to blame someone else for using the word you brought up?no you used to term poison, and have given a list of things that are not poison. arguing that water us poison as it very occasionally leads to death, is much the same as arguing that sharks are poison as they very occasionally kill people and nether are poison at all, though potentially harmful if your terminally stupid or at least with sharks extremely unlucky
ironically, an excess of water can be harmful as it removes poison from your body, most notably sodium, so it's it's anti poison properties that make it harmful
