LOCKDOWN DEBATE: Some suggest that marginalising unpleasant and offensive people – not doing business with them, not giving them a platform, not employing them in your business – is an entirely reasonable, personal decision. When do such actions become a systematic marginalisation of certain views – and what’s wrong with marginalising repulsive views anyway? Many seem eager to ‘fight fire with fire’ – calling out the double standards of their opponents in a tit-for-tat round of cancellations – but how can we expect that to lead to a greater range of opinion and debate? Perhaps we need to ask a fundamental question: what does it mean to live in a genuinely tolerant democracy? Nick Buckley MBE, Alex Deane, Claire Fox, Helen Pluckrose and Calvin Robinson discuss.
