I just watched the first few minutes and one other thing struck me - the fact the mother has used Dorian as a model for her art, for images she clearly reproduces and sells, since she was very young - and Dorian has apparently had no say in that.
It’s like putting endless photos and videos of your child/teenager on FB/YouTube, only worse, because shes continuing to do it and she’s making money from it. Zero respect for her child’s boundaries/privacy.
I got up to the bit where Dorian says she has a complicated relationship with her mother, and thought, yeah, you’re not kidding. I’ll bet that along with rejecting the whole girly stereotype thing, and being a lesbian in a world where lesbians are increasingly pressured to identify as male, a huge part of what’s behind her “transition” (she’s seriously just about the most obviously female person you could imagine, in every way!) is the way her mother has exploited her for her professional gain, and continues to do so, and has trampled over her boundaries. All while being “woke” and “accepting” and generally full of shit and lacking in any real parental protectiveness.
(Not exonerating the father, btw, either: I don’t know if he appears later in the programme but no mention of him initially: if he hasn't bothered to take part in his daughter’s upbringing then she’s had two crappy parents, which won’t have helped.)
To me it looks very like the “identifying as male” bollocks is pushback against a mother who has prioritised her art over her daughter; who has literally made a career out of putting her daughter’s life/development on show - who has definitely not put her needs first. Cry for help/attention, effectively. But clearly she [Dorian] is completely unaware of that.
