Well, I knew what Gaslighting was, mostly from the various film versions of Gaslight (though primarily the Charles Boyer/Ingrid Bergman one. But I don't really understand the context of these people's comments to you here. AFAIK it's about secretly planting clues and implications that slowly start to make the other person unsure of their own sanity. I get your point that in a society that has been brainwashed in many ways by the powers that be and which spends billions of dollars trying to get people to believe in illusions instead of reality that something that gets them to question reality and their own perceptions of the world can only be a good thing. I'm not sure I'd use the word 'gaslighting' for that though. I think it's because I've had negative associations with the word for so many years that I wouldn't want to use it to describe a process that is actually healthy and beneficial, i.e., questioning what's behind the institutions of power that rule this globe.

I love those quotations, especially Chris Hedges (which I hadn't heard before) and Krishnamurti (which I had.) I am going to save these.
