Racial injustice has occurred throughout U.S. history, targeting African Americans as early as the 1930s when they had to fight for equal rights and treatment. Racial injustice persists today in various forms, including through groups like the Ku Klux Klan, and can only be defeated by uniting against it and walking in each other's shoes to overcome prejudices. Professionals in all fields still face challenges of racial injustice and must continue fighting for equality.
