Here's isn't high effort. It's a bunch of canned "gender critical" arguments that we've all seen a thousand times before combined with arbitrarily dismissing all of the evidence in favor of gender affirming care for kids using specious reasoning and then citing long debunked studies like the "80% desistance rate" one.

Their bias is even more clearly demonstrated by the fact that the first study they cite isn't hosted on any legitimate source of medical science, but on "transgendertrend." That demonstrates that they didn't find their data via PubMed or Google Scholar or anything, they found it by looking for cherry picked medical studies from people with an anti-trans agenda.

It's transphobia and perpetuation of misinformation disguised as a polite conversation. It's the same level of "discourse" as "blacks make up 12% of the population and commit 50% of the crime."

Edit: not only is it arbitrary and awfully convenient for cherry-picking purposes to leave out longitudinal studies of mental health, since mental health is what's at stake here, and "objective" measures are susceptible to many confounding variables and often not relevant, and standardized tests of mental health are regularly used to ascertain the efficacy of many procedures related to psychology, there are also studies that use "objective" measures such as the ones he wanted, where applicable. Here's one that's somewhat infamous due to one of the young adults getting a fatal complication from a surgery, but such surgeries are not performed on minors, and are not particularly dangerous, so it's largely irrelevant: https://pubmed.ncbi.nlm.nih.gov/25201798/. Here's a list of 16 studies on this: https://www.psychologytoday.com/us/blog/political-minds/202201/the-evidence-trans-youth-gender-affirming-medical-care.
