Paddle your canoe up the River Thames and you will come round the bend and see a forest of huge totems jutting into the sky. Great shiny monoliths in various phallic shapes, they are the wondrous cultural artefacts of a remarkable tribe. We all know someone from this powerful tribe but we very rarely, if ever, ascribe their power to the fact that they have a particular tribal identity.
I think this tribe, a small minority of our native population, needs closer examination. In the UK, its members probably make up about 10 per cent of the population (see infographic below); globally, probably less than 1 per cent. In a phrase used more often in association with Operation Yewtree, they are among us and hide in plain sight.
