Final answer:
LULAC and the GI Forum focused on fighting discrimination and advocating for civil rights, including equal educational opportunities and voting representation for Mexican Americans.
Step-by-step explanation:
LULAC and the GI Forum initially contended that Mexican American civil rights activists needed to focus their efforts on combating discrimination and fighting for greater civil rights. This included ensuring equal educational opportunities, as evident by their protest against segregation of Mexican American children, which was ruled a violation of the Fourteenth Amendment.
They also addressed issues regarding bilingual education, Mexican American history, and equitable voting representation. These organizations helped launch a concerted effort to lift Mexican Americans out of social, educational, and political marginalization, as reflected in their campaigns for school improvements and legal victories in significant court cases, like Mendez v. Westminster.
