I think it was powerful that Meghan choose voices from that side of the debate that were (in their own ways) thoughtful and who could perhaps have partially understood some of JKR's perspective (like being on the recieving end of cancel culture for contrapoint).
I think it's important to find points in common rather than seeing people who disagree simply as "the enemy".
I was impressed by Noah's thoughtfulness on detransistioners and seemed sympathetic to parental concerns about transitioning. I was waiting for the clincher of how Noah knew transistioning was right for Noah and how had taken time coming to that conclusion. But it was all trust in HCPs and Noah was still so young.
What Noah lacked was the perspective older people have, of how older women who have struggled with puberty, same sex attraction, gender stereotypes or sexual harassment and how we got through that discomfort of growing into women, and how it didn't mean that we weren't really women, or couldn't want to have children or breastfeed some day (obvs not all do!) But that outside the pressure cooker of school as a teenager, we could find out tribe of other non conforming women, or our unfeminine career/interests or same sex partner or feminism or all of it.
Instead Noah and parents trusted that HCP knew what was best for Noah. They didn't have the perspective that actually all of this is new, experimental and fundamentally based on an untrue premise - that all people with cross sex identification or even most of them are going to always feel that way and so the "kind" thing to do is to medically alter them to be as close to the opposite sex as possible, as young as possible.
Anyway, I've now listened to the final episode, JKR is so intelligent and measured, and brave. Really important series and Meghan and her unique experience and care really brought a lot to the interviews.
