The Guardian thinks of itself as Britain’s fearless liberal conscience, trigger-sensitive to racist ‘dog whistles’ in the language and editorial judgements of everyone except itself. It takes a special interest in cartoons published by right-of-centre newspapers which are accused of bigotry.

When the Murdoch-owned Herald Sun ran a cartoon depicting Serena Williams throwing a tantrum, the Guardian reported that News Corp had ‘come under global condemnation for publishing a racist, sexist cartoon’, supplementing multiple news stories with several condemnatory op-eds.
