Book excerpt: American racism traps Blacks -- even in Africa. Prof. Dennis chronicles the compulsive and repetitious nature of racism and its destructive effects on peoples and societies, Dr. Dennis's observations of the twists of irony and misplaced pride on all sides will provoke a wry smile as well as dismay. During the 1990s, Liberia descended into civil war and anarchy. African-Liberian rebel groups roamed the countryside randomly killing as they vied for power. Doe was killed by a segment of these rebel groups and warlord Charles Taylor eventually became president in 1997.
