A long-standing US anti-pornography campaigning group has advised, promoted and endorsed anti-LGBTQ+ activists and politicians in Uganda, including a governing party member who endorsed anti-LGBTQ+ laws by saying gays “should be castrated”, and a virulently homophobic founder of a “militaristic” Christian boys camp. The revelations about Washington DC-based National Center on Sexual Exploitation (NCOSE) and its spin-offs and affiliates – based on documents, audio and video recordings and open-source materials – raise questions about its recent disavowals of its history of anti-LGBTQ+ positions, and its role in Uganda’s passage last year of laws on homosexuality which are among the most punitive and restrictive in the world.
