Last summer, I was amused to see that organised atheism was facing the possibility of a serious schism. Perhaps it wasn’t so very surprising – most religious traditions end up having one sooner or later. The American Humanist Association (AHA) withdrew a Humanist of the Year award given in 1996 to perhaps the world’s best known non-believer, Professor Richard Dawkins. His offence was questioning the tenets of transgender ideology, which has rapidly replaced gay marriage as the ultimate test of progressive credentials.
