Discrimination and protected classes form the core of civil rights law in the U.S. These concepts address how individuals are treated based on characteristics like race, gender, and religion. The legal framework aims to prevent unfair treatment and promote equality in various aspects of life. Key court cases have shaped anti-discrimination laws over time. From Brown v. Board of Education to more recent rulings on LGBTQ+ rights, the legal landscape continues to evolve. Current debates focus on issues like affirmative action, racial profiling, and intersectional discrimination.
