I have done that a couple times. What was funny one time where I used to work was a conversation that included a dude from Congo. He was indignant at the term AA. We also had a white guy from South Africa. He called himself AA and one of the black Americans tried and call him on it. If not for being so stupid it was funny to watch.
Agree it would be funny if it were not so stupid.
The white Africans from north Africa to Zimbabwe , to South Africa I have met and known get pissed off when they are telling people they are African and an ignorant idiot states they are not black they can’t be.
