Interestingly, I don't think that is "correct" use of gaslighted. It sounds right metaphorically, as you are "igniting" them in a way that "lighting a gas source" would go. However, gaslighting is to sow doubt and confusion in people's self thoughts. I /think/ you could use this to the same end, but I think the initial was specifically not evoking a sense a rage, but one of dependence.

Yeah, you are right. I think the mechanism, to start an outrage vs the perceived outgroup is indeed the same. Once ignited lots of people don’t change their stance, unless you score high on self-reflection perhaps.
