This and also: NDs are often more precise and thorough, thereby often poking holes in NT narratives. Often NTs speak just to impose narratives to improve status and power, and NDs threaten this game.
When this is coupled to the lack of reverence NDs have for the hierarchy (including the binary gender imbalance), NTs try everything to shut NDs down. Often succeeding, bc e.g. interrupting NDs when they already have trouble taking their moment, is easy for NTs.
Also NTs more easily play out other NTs against NDs. They have much more energy and time doing this, too, as NDs will be often absent from meetings to recharge.
