Cisnormativity refers to the societal assumption that all individuals are cisgender, meaning that their gender identity aligns with the sex they were assigned at birth. This concept often marginalizes and invalidates the experiences of transgender and non-binary individuals, reinforcing a binary understanding of gender that overlooks the diversity of gender identities. It shapes cultural narratives, policies, and personal interactions by promoting a limited view of gender that is intertwined with various social constructs and inequalities.
