amazing how she keeps claiming to be black....
And there is a cynical part wondering whether there is just an attempt to reduce the number of successful African-descended people (not even to boost the numbers of European-descended people; it being more about pushing African descendants down rather than lifting European descendants up) by stating that Berry and others are not 'black' and that their success is due to their European ancestry.
A la the Japanese and the Russians after the Russo-Japanese War where the Japanese were 'promoted' by some Europeans conjecturing that Japanese had some [European] blood while the Russians were 'demoted' by some Europeans conjecturing that the Russians had diluted their European blood and had some Asian descent. Russians still would obviously be more European than the Japanese, but at least a fully European people wasn't beaten by a fully non-European one.
Hopefully the 'racism detector' is just throwing off a bad reading, and personally looking far too much into it, and your motives aren't nearly as sinister as the one posited in the last two paragraphs.
