Arizona Attorney General Tom Horne knows racism when he sees it, and he isn't afraid to publicly castigate the most recent agents of race hate. Horne is an outspoken opponent of racism in a state roiling with tensions about "illegal aliens" and "anchor babies." The bigotry Horne especially rebukes? Courses like "Latino literature." If Horne has his way, the Tucson public school system -- serving a student body that's over half Mexican American and, like other districts, already suffering hard economic times -- will lose $15 million in state funding this year unless it terminates its Mexican American Studies program.
