Short version: Dianics at PantheaCon refuse to allow transwomen into their Lilith ritual, the event is dutifully reported on, Z Budapest spews a bunch of transphobic nonsense, hilarity ensues.
What do you think, dear NFP?
Personally, I do not support gender separatism at all; people are people, at core, and sharing is caring, y'all. Genital configuration and social gender presentation aren't enough of a difference for me to suggest that another person cannot understand my own experience. Not to suggest that understanding vastly different experiences is always a walk in the park, but certainly not impossible as some suggest.
As pointed out by jadeserenity, CAYA has released a statement about the event, clearing up their stance on gender inclusiveness.
