A little bit of history never hurt...we did in fact have some hyphenated american group names, my Uncle being a member of the The Italo-American Club, founded in RI (established in 1896) Social Club (no Mussolini pics on the wall, though) in the 50’s. The Franco-American Club was just down the street. Not trying to be a wise guy, just saying what I know to be true.
From personal recollection, I believe Afro-American didn’t come into vogue until middle to late 60’s on the west coast, but certainly no African-American term was in use then...not until later. George Carlin did a great bit on being confused about the whole nomenclature changey thingy with that hyphenated thing in concert in the late 70’s.
I was born in ‘67 and my birth certificate says black. My husband was born in ‘64 and his says negro. My mother was born in ‘42 and hers says colored. Nobody was African American until the late 80s or 90s.
