I too watched this on Richie Heron's Twitter.
That Niamh person said two things that really contradicted his position on gender affirming "care":
- trans people should not be "pathologized"
- the gender affirming model accepts the person's sense of their own gender id at any point in time, which he admits may change from one year to the next, including back to their birth sex. Ie. gender is fluid.
So why on earth are activists like him demanding irreversible medical treatments? For something that isn't a disease, and may not last?
