"gaslighting" does have the specific meaning you describe, or at least it used to, but these days it's mostly just used to mean "saying something I disagree with." It seems to come from a special kind of narcissism in which people are so devoutly convinced of their own moral rectitude that they can't believe anyone might disagree with them in good faith. They're so cocooned in their bubble that they can't process anything resembling a contradictory opinion; it sends them into emotional haywire and their only response is to cry victim. When I hear someone talking about "gaslighting" it significantly lowers my inclination to take them seriously.
