You’d have to specify which talking points you’re looking to verify/falsify. A nonzero amount of people surgically transitioning and then regretting it doesn’t do much good for the verifiably made-up points or eliminationist points that “right wing talking points surrounding Trans issues as a whole” often contain.

Anyway, here’s Some More News talking about detransitioners. His content tends to be a bit on the ranty side but I hope you’ll consider giving it a watch.
