Racists Anonymous: Racists Anonymous is a support group, based on the Alcoholics Anonymous model, which views racism almost as a mental illness.  The group was created by Sunnyvale, California United Church of Christ pastor Ron Buford over his frustration with typical attempts to deal with race issues which merely either left him feeling angry, or white participates leaving feeling guilty.

As of September 2017, 90 congregations in four countries have requested the program's kit, and several have established their own programs independently.
