The concept of professionalism is embedded into all aspects of nursing education and practice yet is rarely critically interrogated in nursing scholarship. This paper describes how professionalism in nursing is based on whiteness. When actualized, this oppressive construct homogenizes individuals' identities to assist nurses in building and wielding power against each other and against patients, and results in dehumanization and disconnection. Foregrounding an ethic of authenticity as a practice of resistance against white professionalism offers an alternative possibility for how nursing could be taught, practiced and theorized. As such a practice must begin with oneself, the authors outline a reflexive process from which to begin this work.
