noun
- One who engages in wrongthink.“Twitter/X is clever enough not to outright ban wrongthinkers as that would be noticeable. Far better to not notice wrongthinkers. This is done via what amounts to sending them to a “time out” room where no one else knows they are. The wrongthinker is left to talk to himself.”
