There is always something perverse about trying to explain the law of non-contradiction to someone. If they don't minimally observe it - at least performatively, if not explicitly - then they don't know how to speak, and so, arguably, are beyond the reach of any explanation whatsoever ...
The common thread in various types of 'gaslighting' is that it puts people in the position of trying to make sense of maliciously unintelligible behaviour. From colonial exploitation to domestic abuse to playground bullying, coarse power has been expressed through making the powerless go through hell trying to learn the language of the oppressor, however capriciously that oppressor may play hide and seek with the grammar.
The illusion of narcissistic superiority, the ground of psychopathic internal shame-avoidance fantasies, is maintained by keeping people in the dark and manipulating them. Power exercised through deception is, absurdly, valued above the ability to make sense.
