Incivility refers to a lack of respect or politeness in behavior and speech, often manifesting in rudeness, contempt, or hostility towards others. This term is increasingly relevant in the context of social and political polarization, as it can exacerbate divisions between individuals and groups, undermining constructive dialogue and cooperation. Understanding incivility is crucial for analyzing the broader implications of discourse in contemporary society, where differing opinions often lead to increased hostility and a breakdown of civil communication.
