WPATH is a trans advocacy group with many of its members deeply committed to trans ideology.
WPATH internally built a set of treatment guidelines with little or no external input. The resulting guidelines are essentially students marking their own homework, recommendations created in an echo chamber.
Their guidelines were released at a time when there was little or no decent clinical research to guide healthcare professionals and so gained favor as the only horse in the race.
As the only available guidelines, many health bodies adopted their initial recommendations.
WPATH then embarked on a frog boiling exercise with regular updates that gradually changed the thrust of their guidelines further and further away from their initial position. This gave us such gems as medical professionals advocating for a eunuch gender in WPATH 8
The tide is turning - many healthcare bodies are now looking carefully at their blind acceptance of what WPATH are recommending and then discretely dropping them.
Remove the blind acceptance of what WPATH recommend and the whole 'everyone agrees' house of cards collapses. 'Everyone agrees' is not a consensus in this case it simply reflects that everyone is reading from the same set of recommendations.
Where the internal workings of WPATH have been exposed - for instance in the so called WPATH files - it is clear that their advice is not well founded. Examples are clear instances of clinicians recommending irreversible treatment to patients that are unlikely to be able to give informed consent, patients that are too young to give informed consent and patients that have other serious mental health issues. Read the files, they are primary evidence as to how WPATH works internally.
The workings of WPATH were further exposed in disclosure associated with United States v. Skrmetti where it became clear that WPATH adjusted the wording of their recommendations in order to try to prevent legislators reining them in.
WPATH chose not to include things like minimum ages for drug and surgical treatments to reduce pushback from the general public. WPATH also chose to doctor language within documents replacing phrases like 'insufficient data' and 'limited data' with 'medical necessity' and 'evidence based'
A medical body that finds it necessary to obfuscate and reframe its recommendations to deceive the general public into acceptance is an advocacy group.
