The U.S. Constitution protects the rights of minority groups primarily through the Bill of Rights and subsequent amendments, which safeguard individual liberties regardless of majority opinion. For example, the First Amendment ensures freedom of speech, assembly, and religion, enabling minority voices to be heard. Additionally, the Equal Protection Clause of the Fourteenth Amendment prohibits discrimination, reinforcing legal protections against unjust treatment based on race, gender, or sexual orientation. These constitutional protections aim to promote equality and uphold the democratic principle that all citizens are entitled to their rights.
