UNTIL TEN years ago Cecil Rhodes was just one white British imperialist among many. Then, in 2015, Chumani Maxwele, a young black South African, gave a “poo shower” to Rhodes’s statue at the University of Cape Town, built on land Rhodes bequeathed. In doing so Mr Maxwele set off a global campaign called “Rhodes Must Fall”. The Cape Town statue did come down but others, notably one at Oriel College, Oxford, remain standing.
