“Indeed, what is acceptable for white people to call African Americans and for black people to call themselves has evolved over the last century. The standard term has shifted from “colored” to “Negro” to “black” to “African American” as people sought to redefine themselves and their place in America.
Now, in 2020, “people of color” often is used to refer to the collective group of non-white Americans. It is offensive to single blacks out as “colored.” That, in part, is because of the painful segregationist history associated with the term prior to the mid-1960s. “Colored-only” restrooms and water fountains are examples of harmful relics of the Jim Crow South that black people had to fight, and die, to remove from American culture.”
