First, nice article!
Second, from my experience...
People who gaslight you are trying to control you. Period. No amount of logic, reasoning, discussion, defense, clever retorts, or other interaction will help, because they are manipulative people. The best course is to get away from them and permanently divorce yourself from them. Gaslighting is a symptom of some pathology; it is not just a personality quirk or an off-the-cuff defense mechanism, especially when chronic. Sure, everyone says stupid, hurtful things, but when it’s chronic it’s time to pack your bags, because this is a fight you won’t win.
