* conversion therapy in the form of talk therapy [2], for which, the Independent Forensic Expert Group (which functions under the auspices of the International Rehabilitation Council for Torture Victims) has said [2a]:
"All forms of conversion therapy, including talk or psychotherapy, can cause intense psychological pain and suffering. All practices attempting conversion are inherently humiliating, demeaning, and discriminatory. The combined effects of feeling powerless and extreme humiliation generate profound feelings of shame, guilt, self-disgust, and worthlessness, which can result in a damaged self-concept and enduring personality changes"
* The "Rapid Onset Gender Dysphoria (ROGD)" hypothesis, the original paper of which was revised to say something completely different after it was shown to lack scientific basis [3] [4]
* right-wing propaganda about sex and relationships [5]
* ending all transition healthcare for adults up to age 25 [6]

I realize I sound like Charlie from It's Always Sunny, but it's all there. These organizations have deep links to various right-wing networks and are all attempts to launder right-wing, unscientific ideas into the mainstream.
As an autistic person with a history of trauma, abuse and mental illness, I'm deeply offended at the insinuation that I and people like me can't tell if they're trans or not. Being trans is not mental illness, it's human variation.
Not intervening in puberty for someone who will grow up to be a trans adult also does permanent harm, resulting in tens to hundreds of thousands of USD in surgery and other costs, and (more importantly) a lot of pain. The fact is that early intervention prevents a lot of suffering down the road. If your moral calculus doesn't take that into account it is illegitimate.
