Unite the Right rally [SEP] Counter-protesters
Those who marched in opposition to the rally were unified in opposition to white supremacy, but "espoused a wide array of ideological beliefs, preferred tactics and political goals. A large number were ordinary residents of Charlottesville who wanted to show their disdain for white supremacist groups, particularly after the Ku Klux Klan held a rally in the city on July 8." Ahead of the rally, an array of "faith-based groups, civil rights organizations, local businesses, and faculty and students at the University of Virginia" planned counterprotests. In July 2017, the ecumenical and interfaith clergy group Congregate Charlottesville called for a thousand members of the clergy to counterprotest at the rally.
