A cartoon about the possible danger of refusing to take a knee
Taking a knee is a gesture of solidarity with the Black Lives Matter (BLM) movement.
Some people, while sympathetic to the cause of tackling racism, feel that they wouldn’t want to take a knee themselves, either because they don’t agree with all of the aims of BLM or because they feel uncomfortable with there being any obligation to enact the gesture, especially because they feel that the gesture contains some elements of supplication (or that if it doesn’t actually contain those elements now, it may well evolve so that it does in the future). Supplication implies adherence to the cause or a pledge of allegiance rather than simple recognition of it or solidarity with it.
The British Foreign Secretary, Dominic Raab, today (18th June 2020) expressed opinions along these lines, stating that he thought the act contained elements of submission. He has been criticised quite widely for this attitude.
The cartoon shows someone being hit in the face by a custard pie, a metaphor for being ridiculed or humiliated.
