"TERF" is an acronym coined by trans activists, which stands for Trans-Exclusionary Radical Feminist. In practice, a huge and diverse cross-section of women are currently being called TERFs and the vast majority have never been radical feminists. Examples of so-called TERFs range from the mother of a gay child who was afraid their child wanted to transition to escape homophobic bullying, to a hitherto totally unfeminist older lady who's vowed never to visit Marks & Spencer again because they're allowing any man who says they identify as a woman into the women's changing rooms. Ironically, radical feminists aren't even trans-exclusionary — they include trans men in their feminism, because they were born women.
But accusations of TERFery have been sufficient to intimidate many people, institutions and organisations I once admired, who're cowering before the tactics of the playground. "They'll call us transphobic!" "They'll say I hate trans people!" What next, they'll say you've got fleas? Speaking as a biological woman, a lot of people in positions of power really need to grow a pair (which is doubtless literally possible, according to the kind of people who argue that clownfish prove humans aren't a dimorphic species).
