I just read Irreversible Damage by @AbigailShrier about the phenomenon of soaring rates of F to M transition in girls and young women. Bravo to her for highlighting this, it should be a subject of societal concern — why is it happening, what are the risks? (Thread) I found it puzzling however that the book offered a purely sociological theory — that girls are choosing to transition due to social contagion, subtle pressures from professionals, and a desire to alleviate pains of anxiety, depression, isolation. To me, this is dubious.
