Political discourse affects societal norms and values by shaping the conversations and narratives that define a culture's political landscape. As leaders and influential figures engage in public dialogue, they establish what issues are considered important and acceptable within society. This can lead to changes in public attitudes, as the language and themes used in political discussions often reflect or challenge existing norms. Moreover, ongoing discourse can legitimize certain viewpoints or marginalize others, thereby affecting how people perceive issues like immigration, equality, and justice, which can have long-lasting impacts on policy and culture.
