Final answer:
Mexicans and Mexican-Americans have historically responded to discrimination through political activism, forming unions and civil rights organizations, and challenging segregation and advocating for educational reforms.
Step-by-step explanation:
The response of Mexicans and Mexican-Americans to discrimination in the United States has been marked by significant political activism and advocacy. Throughout the 20th century, this community has fought against racial discrimination through various means, including the formation of unions, legal action, and civil rights organizations like the League of United Latin American Citizens (LULAC). During the 1930s, Mexican-American students challenged segregation in educational institutions, and in the 1960s, along with the African American civil rights movement, Mexican American activists called for Brown Power and employed the term Chicano to express pride in their cultural identity and to demand improvements in education and bilingual instruction.
