I want to know the answer to the following question:
What movement sprouted this change in rhetoric?
All the background I'm provided with is that "During the American Civil Rights movement of the 1950s and 1960s, some African-American leaders in the United States, notably Malcolm X, objected to the word Negro because they associated it with the long history of slavery, segregation, and discrimination that treated African Americans as second-class citizens, or worse.". Is that enough to answer the question?
Answer: no
