Zoe Strimpel argues that the culture war is no fake or proxy war - but rather ideas about what is acceptable to know, to teach and to think.
Thirty years after the US sociologist James Davison Hunter wrote his book 'Culture Wars: The Struggle to Define America', Zoe looks at how those ideas are playing out around the world today.
'There is a sense of menace about,' she writes, 'of pent-up, complicated grievance. I worry that the culture war could tip into something far more deadly.'
