Disclaimer... if I accidentally use the wrong language I apologise. I'm trying my best. And I'll be using the pronouns we were asked to use.
It was more balanced than I expected. But still biased, and all questions had to be handed in before the session and pre- vetted.
The panel was led by someone who didn't say how they identify. (If they did I didn't hear) but in the 'old days' would be a butch lesbian. There was an enby, afaik they were born female, mentioned using he/him at one point before becoming they/them. 2 TW. And a TM.
They talked about their journey to become who they are now. It was interesting. No mention from the older TW about how her then wife coped/felt other than they got divorced as a result. I felt sorry for them all, it sounds like they had some bad times (so have I so that's not exclusive to trans people, but I have empathy)
They mentioned sharing pronouns and said you should never feel you have to, but also don't do the jokey "well obviously my pronouns are..."
So far so good.
Then we had
Sex and Gender are the same thing. Feminists pretend they aren't so they can deny our existence.
Sex isn't fixed or binary because of seahorses. Not only do male seahorses carry the eggs, they also fertilise them themselves. (No idea if that's true. DS said if it is are seahorses technically clones?).
I wanted to ask why that's relevant to humans, I mean seahorses can breathe underwater and I can't so we aren't the same. But we weren't allowed.
One of the questions was from a 12 year old who thought they were trans. The answer from one of the TW was "tell your parents. If they don't believe you I can't say what i recommend as it's illegal". If that isn't a veiled recommendation to threaten self harm/suicide I don't know what is. 
And some things I didn't fully understand. One of the TW kept mentioning a book, should have made a note of the title, about trans children in history, or the medicalisation of them. Or something. I couldn't work out why experimental surgery in the past,which we don't do on children any more, was therefore meant to be a sign that trans people exist. Or something.
All the books they mentioned were firmly on the side of TWAW, nothing from the 'other side' or in the middle of the road as it were.
Finally, if anyone recognises this talk and was there maybe you can clarify if I've got any of the content wrong. I don't think I have. That's certainly how I understood it. And there were people there who I overheard afterwards saying they didn't know anything until then, there were also some younger teens there. So they've learned some wrong 'facts' and may well go away believing them.
Sorry its long!
