Racism against black Americans is when people treat black people differently because of their skin color. It can mean not being treated the same as other people, not getting the same opportunities or being treated unfairly. Racism against black Americans has been around for a long time. People in the past treated black people differently and made it hard for them to get good jobs and to have a safe place to live. To this day, black people still experience racism - people sometimes make negative comments or don't give black people the respect they deserve. Racism against black people is wrong and it's important for everyone to stand up for their rights.
