She has an overblown sense of her own medical expertise.
This I agree with. When she said something that was flat wrong about my own area of medical expertise, I challenged her, politely, with an explanation and references. She doubled down.
She reminds me very much of a medical student who's done all the reading, can recite the list of rare complications of whatever, but who hasn't the clinical experience to put them into any sort of context.
So, in the past few Jazz episodes we have her repeating that Jazz has a puberty blocker induced form of Prader-Willi (not possible, it's a specific genetic disorder, and Jazz doesn't present that way anyway). And, in the latest, rattling off all the horrors that a head injury can cause, including delayed death. And, well, maaaaaybe. But most falls end in nothing worse than the odd bruise. I see nothing in the footage we have to suggest this fall has caused even the most minor of head injuries.
It's endless catastrophising, which sounds convincing, but doesn't stand up if you have any relevant knowledge. And that undermines how much weight I give her when she talks about the dire and predictable consequences of gender reassignment surgery.
I know nothing about those surgeries. But, when I know she's wildly exaggerating or just plain wrong on things I do have professional expertise in, then it means I take everything else with a pinch of salt. Which is a shame, because it undermines her core message.
