Mia Hughes / “Mia Ashton” vs. transgender people

Mia Hughes, aka “Mia Ashton” and “Mia Sedley,” is a British writer and anti-transgender extremist.

Hughes is associated with anti-trans group Canadian Women’s Sex-Based Rights (caWsbar) and is closely associated with American anti-trans extremist Michael Shellenberger. Hughes is key author of The WPATH Files, a 2024 propaganda piece featuring Hughes’ distorted explanations of non-public communication by WPATH members.


Hughes is from Cheshire, a rural county south of Liverpool and Manchester.

Hughes taught in Taiwan for almost ten years after college. Hughes met a Canadian citizen there, and they married there and had their first child there. Hughes and spouse moved to Ottawa in around 2011 and now have three children. Hughes was a stay-at-home parent who began homeschooling their children: “I got to spend a precious decade with my children while they were young.”

Hughes has published under several names, including:

  • “Mia Sedley”
  • “Mia Ashton”
  • “Mia Hughes”

Hughes has written for anti-trans publications The Post Millennial, The Critic, Lesbian and Gay News, Environmental Progress, and Gender Dissent.

Anti-transgender activism

Hughes was radicalized by a tweet by J.K. Rowling on December 19, 2019 that supported anti-trans activist Maya Forstater:

Hughes stated in 2022:

There were signs that I wasn’t truly woke, and then it was a very rapid change from the tweet, JK’s tweet. I read it and I just couldn’t understand what all the fuss was about. And I even asked woke friends, I went into it on Facebook: “I don’t see what the fuss is about.” And that was the first time that I experienced something of a pile-on, where they were all calling her a TERF and trying to show me why it was hateful, and I just couldn’t see why it was hateful at all. And so I plunged down a rabbit hole that possibly I wish I’d never gone down. Then I emerged as a fully fledged TERF. I was outraged about what I had learned and just started tweeting about it.

Hughes was soon suspended by Twitter for anti-transgender posts, then created a new ban evasion account.

Hughes writes for anti-trans extremist Michael Shellenberger. A profile at the non-profit Environmental Progress stated Hughes focused on “the controversy of pediatric medical transition and how trans rights collide with the rights of women and the LGB community.” Shellenberger retained Hughes to write at the for-profit Substack and podcast called Public. Hughes has contributed the majority of anti-trans content there. Hughes continues to do anti-trans work under the aegis of Environmental Progress, including The WPATH Files, a 2024 propaganda piece featuring Hughes’ distorted explanations of non-public communication by WPATH members.

Maëlys McArdle profiled Hughes in 2023:

Mia is a founding member of caWsbar, an advocacy group focused on one issue: denying trans people rights. It was part of a wave of anti-trans organizations using the sex-based rights dog whistle. She along with a local group of bigots are linked to multiple transphobic incidents in Ottawa, which I’ve previously covered hereherehere, and here.

Mia Ashton participated in the mob along with National Post columnist Rupa Subramanya and another active member of that local group, @MrsDrBee on Twitter.
