“We’re also happy to have non-binary people provided they have a vagina; but not non-binary people with a penis because we have to draw the line somewhere.”
To me I think it means they will allow trans men, presumably no matter how well they pass as men, to attend as long as they do not have a prosthetic pens. So Buck Angel,who has spoken publicly about retaining a vagina, or the trans man in that poster about menstrual bleeding could (possibly)attend if they wanted to?
India Willoughby , Kelly Maloney and Janet Mock who have had full surgery, and are quite open about it, could attend.
Blaire White however, despite her appearance, could not attend as she speaks quite openly about not having had genital surgery (although the chances of her wanting to go are as non-existent as that of the posters on here)
