LIBERALS call him a racist, a crank, and a white wannabe. Black conservatives are outraged by his latest book's "twisted half-truths" and "dubious assumptions". But Bombay-born Dinesh D'Souza is no stranger to controversy, for he exults in being an iconoclast. He has bashed everything from militant feminism to homosexuality, multi-culturalism, affirmative action, and now liberalism. At 34, D'Souza has followed up his first bestseller of 1991, Illiberal Education: The Politics of Race and Sex on the Campus, with another potential success, The End of Racism, that has put him at odds with almost every one.
