Here's the actual letter:

They say that Sodha's article makes a couple of untrue allegations. Specifically: falsely claiming there are “long term health consequences” for trans young people accessing gender-affirming care, falsely claiming young trans people have “surgeries”
I find this very odd. McConnell has complained at not being able to breastfeed because the surgeon didn't say that a radical double mastectomy would remove milk ducts. Is that not a long term health consequence? What about vaginal atrophy? Also well documented. Or the second baby being born early and with a poorly developed placenta - a documented side effect of testosterone on developing foetuses.
According to McConnell's wiki page, McConnell was 23 when they decided they were trans, immediately started on T and had a double mastectomy a year later.
Keira Bell was 20 when she had a double mastectomy. 16 when she was put on testosterone.
I would consider them both young people.
I couldn't be bothered to read the whole thing. But it ends with a demand that men and women shouldn't have the right to comment on trans people. As ever, the respect is a one way street
