Populism is fuelled in part by political correctness that tells people their views cannot be aired. That was one conclusion of a panel of experts last week at a launch of a report by the think tank Demos. Those discussing the report, “Mediating populism”, thought that if views are silenced, they do not disappear, they only go underground to reappear more vigorously in the future, trampling on bounds of “acceptable” discourse. For example in Germany, where the Third Reich is taught as the most sombre warning, the suggestion that ordinary soldiers could be remembered well has morphed into a recommendation from a far-right leader that alarmed many Germans. The co-founder of the increasingly popular Alternative für Deutschland said Germans should be proud of soldiers’ actions in the two world wars just as Brits are proud of Nelson or Churchill.
