The American Civil Liberties Union (ACLU) is a group of people who work together to make sure that everyone's rights are protected, no matter who they are or what they believe. Imagine you and your friends are playing a game and one person gets picked on or treated unfairly. The ACLU is like the superhero who steps in to make sure that everyone can play the game fairly and have fun.
The ACLU is especially concerned with making sure that people are not unfairly treated by the government, like the police or schools. They want to make sure that everyone is treated equally and that nobody is punished for speaking their mind or practicing their religion in a way that doesn't harm others.
They do this by taking legal actions, like going to court, to protect people's rights. They also work to educate people about their rights so that they can stand up for themselves and others.
Without the ACLU, some people's rights might be ignored or forgotten, but the ACLU works hard to make sure everyone is treated equally and fairly. It is important to remember that everyone has rights and the ACLU is there to help protect them.
