Wow, that was the most symmetrical path to a solution I've ever done

Found This about Dr Who:
Through all his incarnations, Doctor Who has fought selflessly to ensure the survival of all manner of life forms across the Universe.
But now an international group of academics has branded the heroic Time Lord ‘thunderingly racist’.
The Doctor’s new foes claim that his dismissive attitude towards black companions, his contempt for ‘primitive’ people, and even his passion for cricket are all proof of a reactionary ‘whiteness’ pervading his adventures.
Their concerns are published in a new book, Doctor Who And Race, which says the BBC programme is based in attitudes ‘that continue to subjugate people of colour’.
