"By the late 1960s, the social progress achieved by group in the United States such as the Black Civil Rights Movement (1955–68), had legitimized the racial identity word black as mainstream American English usage to denote black-skinned Americans of African ancestry. In the 90's, "Black" was later displaced in favor of the compound blanket term African American. Moreover, as a compound word, African American resembles the vogue word Afro-American, an early-1970s popular usage. Currently, some black Americans continue to use the word nigger, often spelled as nigga and niggah, without irony, to either neutral effect or as a sign of solidarity.[11]"

"Cultural: Addressing the use of nigger by black people, Cornel West said, “There’s a certain rhythmic seduction to the word. If you speak in a sentence, and you have to say cat, companion, or friend, as opposed to nigger, then the rhythmic presentation is off. That rhythmic language is a form of historical memory for black people... When Richard Pryor came back from Africa, and decided to stop using the word onstage, he would sometimes start to slip up, because he was so used to speaking that way. It was the right word at the moment to keep the rhythm together in his sentence making.”[16] Contemporarily, the implied racism of the word nigger has rendered its usages social taboo. In the US, magazines and newspapers often do not use it, instead printing “family-friendly” censored versions, usually “n*gg*r”, “n**ger”, “n——”, and “the N-word”; however, historians and social activists, such as Dick Gregory, criticize the euphemisms and their usage as intellectually dishonest, because using the euphemism “the N-word” instead of nigger robs younger generations of Americans of the full history of Black people in America."
