Singing "slack" songs about women was the popular thing to do. Anthony B did not believe in degrading women and chose to pen politically-slanted songs instead.
Anthony B is a member of the Bobo Ashanti branch of the Rastafarian movement. "Bobo Dreads", as they are known, are recognizable by their long robes and turbans. The strong Afrocentric pride and the other Rastafarian beliefs (or "overstandings" as Rastafarians prefer to call them) which Anthony B holds are reflected in his songs.
