Journalist Johann Hari has stated that Roberts' writings defended acts such as the Jallianwala Bagh massacre, the Second Boer War concentration camps for Afrikaners during the Second Boer War, and mass internment in Northern Ireland (Operation Demetrius). Hari also wrote that Roberts made a speech at the expatriate South African Springbok Club, which flies the apartheid-era flag of South Africa and calls for "the re-establishment of civilised rule throughout the African continent". Roberts said that he did not realise the Springbok Club was racist when he took on the speaking engagement.
