'Oxford dons have warned students that freedom of speech is at risk as a trans row engulfs the university.
More than 40 academics - including Prof Richard Dawkins, the evolutionary biologist, and Prof Nigel Biggar, the theologian - have intervened in support of a planned appearance at the Oxford Union by Prof Kathleen Stock, a leading feminist, in a letter to The Telegraph.'

Letter includes:
'“Professor Stock believes that biological sex in humans is real and socially salient, a view which until recently would have been so commonplace as to hardly merit asserting.
“Whether or not one agrees with Professor Stock’s views, there is no plausible and attractive ideal of academic freedom, or of free speech more generally, which would condemn their expression as outside the bounds of permissible discourse.”'
