He has been its editor since 1996. Topics range from men and violence to boys becoming men; fathering to male survivors of abuse; and men and feminism, men's health, GBTQ issues.[3] Voice Male emphasizes "the social transformation of masculinities in the world today."[3][4][5] Okun is known for his outspoken views against gender-based violence and advocating that men must take more active roles in preventing violence.[6] He is a frequent op-ed contributor to Ms., V-Day, AlterNet, and other publications,[7][8] and the editor of two books: The Rosenbergs: Collected Visions of Artists and Writers and Voice Male: The Untold Story of the Profeminist Men's Movement.[3]
