Trilby Langton vs. transgender people

Trilby Langton, also known as Tilly Langton, is a British psychologist and anti-transgender activist. Langton is a member of Explore Consultation and Integrated Psychology Clinic, which promote a kind of anti-trans conversion therapy called “gender exploratory” therapy. Langton is associated with anti-trans hate group Society for Evidence-Based Gender Medicine and presented at their 2024 conference.

Background

Trilby Alice “Tilly” Langton was born in December 1982. Langton earned a doctorate from University of East London in 2013. Langton was a clinician at the Tavistock Gender Identity Development Service (GIDS), the English children’s gender clinic that was closed down in 2022.

Anti-trans activism

Langton was part of a group which promoted ‘gender exploratory therapy’ together with anti-trans groups alongside pro-trans groups when training NHS staff. On June 16, 2021, Langton, Anna Hutchinson, and Anastassis Spiliadis met with anti-trans politician Kemi Badenoch.

2024 Cass Review

As part of the Cass Review, the University of York was commissioned to undertake an evidence review, and Langton was engaged to design the review methodology.

On December 17, 2024, Abbey Edward published a letter in The Daily Hampshire Gazette in response to a guest column: “What the writer did not tell readers is that Hillary Cass, for whom the review is named, has no previous experience working with trans youth, did not employ any actual trans people, and stacked her methodological team with prominent anti-trans actors, such as Tilly Langton, a known conversion therapy proponent.”
