The rich old racist woman was on a power trip. It's that simple. She was trying to make Ms. Fulani say very specific words and it's a RL equivalent of what internet trolls call 'owning'. Ms. Fulani knows this and is correct to call it out and well done to her.
Is it wrong that an 83 year old had to retire? Not really, it happens all the time. She was simply held to standards we would all be held to #RoyalRacism
