It's obvious why young 'transitioners' are predominantly female, given what we know about social contagion, and that it's not even particularly irrational to want to escape growing up as the despised and abused sex.
I'm more concerned, and angry, about the failure of policy makers to protect girls and women, by uncritically exposing them to unscientific gender theories and harmful medical practices.
Medical transitioning is much more 'successful' in females than in males, because of the incredible, and irreversible, transformative effects of testosterone. So a woman can afford to wait until much later, by which time she might have thought better of the idea, or at least mitigated some of the medical harms.
Yet, everywhere, middle-aged men are proselytising for early FtM transition, including use of PBs, despite knowing nothing about growing up as a woman, and themselves having very different transitioning 'needs'.
According to Blanchard, three-quarters of male heterosexual transition is driven by a paraphilia which is a manifestation of mature male sexuality. So, they grow up, have a family, and then transition, but feel sad because T already did a number on them. All their campaigning for PBs is a futile exercise in projection.
Hence, they spend the rest of the time arguing that anyone who correctly observes them as male is a bigot. Two pronged attack. Destroy the health of young women, pointlessly. Force the rest of us to live in a stupid mind-control dystopia.
