That interviewer just wasn't getting it unfortinately even when he fully explains it she went down the route of context isn't a factor.
Not that I have a place to comment as an expert being white, but the bit abput Africans and Black Americans reminds me whem I worked away at 19 and we had a large group of staff from Kenya, who would be at pains to tell people they were not the same as the staff from the carribean, they would say "we are african, they are not"., I will be homest was the first time really I had heard black people actively saying don't class me as the same as them much lile I would say some yank is europen just because they are white.
Yeah it is fucking cringe the way she sets out with an agenda and won't be budged. Putting words into his mouth and forcing something clearly aimed at a whole other audience through the prism an assumed uk viewer and lenny henry. Think it was well handled imo.
