"Second-Class Citizens" refers to individuals or groups who are treated as inferior to others within a society. This status often results in limited rights, opportunities, and access to resources compared to those considered first-class citizens. Discrimination based on race, gender, religion, or socioeconomic status can contribute to this classification. Historically, many societies have marginalized certain populations, leading to systemic inequalities. For example, during the Civil Rights Movement, African Americans fought against being treated as second-class citizens in the United States. Such struggles highlight the ongoing fight for equality and recognition of all individuals' rights.
