I was about to ask how on earth 'black' can be conflated with 'African American' but I will stand down.
Over time here here in Ameristan, terms for black folk have been replaced.
The old one becomes offensive, & a new one was introduced.
"Negro" replaced ******.
"Colored" replaced "negro".
."Black" replaced "colored".
"African American" replaced "black".
This misnomer is now applied (by Bruno-like Ameristanians) to all blacks.
Note: "People of color" won't replace any term for black folk
because it includes a broad range of other races, including
even whites of mixed race or Spanish origins.
