“I’m just playing Devil’s Advocate.”
The origin of this term, taken form the Catholic Church, is nearly literal: a member of the church was given the role of arguing against a candidate for sainthood in order to draw out their flaws and prevent misleading evidence from canonizing the unworthy. In modern times, it is used during debate or discussion to explore an alternative point of view, whether or not it is abhorrent. In a room fill of like-minded people, one plays the role of Devil’s Advocate in an attempt to speak for another.
People need to stop doing this.
