Warriors for Social Justice examines the contributions of Mexican American activists to the nation’s democratic values by concentrating on the activism of Maria JimÉnez (1950–2020) in Houston, Texas. Linda J. Quintanilla documents how JimÉnez and other activists advanced social justice by promoting our nation’s best virtues, especially equality. Quintanilla describes JimÉnez’s lifelong battle against injustice, be it racist, sexist, or anti-immigrant animus. The Immigrant Workers Freedom Ride in 2003, only one of her many impressive achievements, delighted her the most.
