In August of 2017, the Unite the Right rally surged through Charlottesville, VA, turning violent and ending in the injury 30 people. Who participates in alt-right movements, and what were the conditions of its possibility? Why is white supremacist ideology resurfacing now, and what makes contemporary white supremacy so pervasive and so dangerous? In this thesis, I forward a Lacanian psychoanalysis of the alt-right, beginning with Donald Trump, and then exploring the movement as a whole, in its relationship to the affect of belonging, the Master-Signifier of whiteness, and masculinity/sexuality as a whole. I conclude with a consideration of potential responses to alt-right violence.
