I asked a friend who just left med school. He laughed and said yes there's lots of evidence supporting this in his profession alone. He suggested you pick up a copy of "Principles of Transgender Medicine and Surgery" ISBN 1138857009 which was a required for one of his courses. It has hundreds of references by MDs,PHDs and the like on the medical side alone.
He did agree that quantity is not quality and recommended to use "Directory of Open Access Journals" to access a large amount of peer reviewed research that does establish the science.
You should contact everyone referenced in the book/research papers and let them know they're incorrect.
Having an open mind to learn more information is not a weakness.I work in data science adjacent and it's fascinating to see new information being uncovered all the time that does fill in missing information about everything we know - or don't know.
