well, just to use one ethnic group..
they used to like being referred to as “colored people” (such as NAACP)
then “Negroes”
then “black people”
then “Afro-Americans’
then “African-American”
then “black people” again
then I lost track.
and of course not everybody is on the same wavelength at the same time, so some take offense even if you’re using the latest “Politically Correct’ term
I wish nobody any offense. Its just difficult sometimes is all
I think “Afro-American” lasted about 3 weeks in the mid 70’s
