It might be useful listening to a Mermaids' training session, forwarned is forearmed so to speak.
Michael Conroy recorded a session and you can hear/read how he asked respectful and challenging questions:

Did you know that your preference for pink sparkles or muddy sports isn’t down to societal expectations of boys and girls. No, it’s written in your chromosomes. And that’s science.

There was also a recording and transcript of a subsequent training session by a school governor who was also a vicar. Apologies, I don't have links for that.
