Suppression, 14

Gaslighting: destroying other’s trust in themselves, by destroying their sense of reality insisting on questioning their certainty of reality and on altered versions of reality.
Projection, blame game, playing the victim: red herring by “blameshifting game”, by dumping the responsibility for one’s negative traits and misdeeds on anyone or anything else; as the Poet said, “Deceit’s favourite role is playing the victim.” Furthermore, doing so in an abusive and cruel way to induce shame and subjugation in others as well.
Nonsensical conversations: countering disagreements and challenges with any kind of illogical conversation in order to distract, confuse, frustrate and blame.
Fickleness and unreliability: constantly changing suddenly from one thing to its opposite, and thus being unreliable, due to both own lack of stability and the deliberate purpose of destabilising others.
Baiting to play cat and mouse: using seemingly innocuous and rational comments as a bait to lure the victim into mindless arguments that degenerate until it becomes clear that their purpose is showcasing their cruelty and tearing down the victim; and keeping at hurting even once they know it, as when they already apologissed for that.
Generalisations: putting blanket labels on things to hide the nuances and dismiss the actual points and facts in them that do not add up.
Deliberate misrepresentation and “mind reading”: twisting or taking to the extremes the others’ legitimate differing views, particularly about themselves, possibly by claiming to know their minds, to pass them off as evidences of their irrationality in order to silence them and instill guilt in them.
Impossible standards: nitpicking, diminishing achieved results, dismissing actual evidence and services received and moving the goal posts eternally, in order to be dissatisfied and criticise destructively for ever.
