Political incivility is different from the everyday incivility described above. According to face negotiation theory, politeness norms require us to avoid challenging others, but political incivility is different because, since it is specific to the political sphere, contestation of views and confrontation are required for a democracy to occur. According to Thomas Benson, "Where there is disagreement, there is a risk of incivility; in many cases, incivility is itself a tactic in political discourse, employed as an indicator of sincerity, as the marker of the high stakes in a disagreement."
