Some of my good male friends, Tories, are sick of terfs. I can see it in their shifty eyes, in the way they won’t quite look at me when terfy issues creep into conversation, but stare gloomily at the skirting board. Terf stands for Trans Exclusionary Radical Feminist, and terfs are women who insist that you can’t change your biological sex, and that the whole notion that some humans are born in the wrong body is not only daft, but catastrophic for our culture and our children.
