Entitled: "Young boys harassing the Baker family, the first African-American family to move into the all white Delmar Village neighborhood of Folcroft, Pennsylvania." Racism consists of both prejudice and discrimination based in social perceptions of biological differences between peoples. It often takes the form of social actions, practices or beliefs, or political systems that consider different races to be ranked as inherently superior or inferior to each other, based on presumed shared inheritable traits, abilities, or qualities. After the Thirteenth Amendment abolished slavery in America, racial discrimination became regulated by the so-called Jim Crow laws, which mandated strict segregation of the races. This legislation that mandated segregation lasted to the mid-1960s. Institutionalized racial segregation was ended as an official practice by the efforts of such civil rights activists as Clarence M. Mitchell, Jr., Rosa Parks, and Martin Luther King Jr., working during the period from the end of World War II through the passage of the Voting Rights Act and the Civil Rights Act of 1964 supported by President Lyndon B. Johnson. New York World-Telegram and the Sun Newspaper August 30, 1963.
