That has to be one of the silliest uses of the PC phrase “ethnically diverse” I have ever seen.
How precisely does one have “ethnically diverse hair”? Hair characteristic of three or four different ethnic groups on different parts of the head? Blonde hair that naturally forms an afro if grown out?
I thought the same thing when I read it.
It’s a tupid use of the phrase, even by PC standards.
Of course, it was written by a “journalist”.
