There is only one definition.
The term “gaslight” comes from the 1944 film Gaslight, which was based on the 1938 play Gas Light by Patrick Hamilton. In the movie, a husband manipulates his wife into doubting her own sanity by dimming the gas lights in their home and then denying that the lights are changing. The term “gaslighting” now refers to a form of psychological manipulation where someone makes another person question their reality.
Some people feel you are pushing an article that is clearly designed to manipulate.
