This looks like an extremely thorough examination and debunking of the massive pseudoscience network behind the attacks against gender-affirming care. Unfortunately, it's 5 hours long. It's hard for me to recommend it personally yet since I don't have 5 hours to watch it. Maybe I will have time, or maybe someone trustworthy will make a summary (or watch the whole thing and recommend it). https://exquisite.social/@thomholwerda/115022546999074004
OK, I'm 45 minutes in, and while the pace is a little slow for my tastes, if you are completely new to transphobic pseudoscience and the attacks on the trans community, this appears to cover the whole thing. It's slow going for me because I know everything in this already, and it is painful watching people who think their gut feelings and middle-school understanding of biology makes them experts on how trans adults and children should receive medical care, and what rights they should have.
