Jess Phillips thinks that transwomen — like me — are not female, but we should be treated as women. She has probably succeeded in upsetting both sides of what has become a toxic debate. Politicians entering these shark-infested waters do so at their own peril. If, like Rosie Duffield or Joanna Cherry, they stand up for science and reason, they put their careers at risk. If they go with the programme that we all have a gender identity, and biological sex doesn’t matter, they end up looking ridiculous, like the ‘jiggle on the stairs’ crew.
