Contested term
A contested term is usually factionally defined. That is, a faction might agree internally on what it means, but to outsiders their definition may be regarded as biased and deological. The glossary makes note of these.
As a simple example, "the left" usually cares more about safety than closure, and "the right" puts its priorities the other way around. Thus they rarely or never agree on fairness. Also, "the left" usually sees evil as the result of a lot of ignorance, especially by "the right". But "the right" usually sees it as something intentional they can "punish".
Almost any label is a contested term and thus requires a specific audit.
