Jen was carrying/wearing a recording device, a dictaphone I believe, inside women's toilets.
On the recent thread, there's a message from a woman who also attended the conference sharing how uncomfortable and distressed this makes her, even in retrospect.
I'm a woman who has no problem with trans people, but doesn't wish to share intimate spaces like bathroom facilities with male-bodied people.
This is why we need third spaces. Women's toilets and the like are there to maintain privacy and dignity, not to validate anyone's gender identity.
