They didn't proceed with it.
My view.
Zero interest to their core voters.
Zero appetite for getting in the middle of trans activists and allies, and a bunch of women. Angry shouty polarised debate. PITA.
Easier to say going to put this on back burner and get left alone. Or at least hassled less.
Tory voters big segment of traditional values types, loads of elderly people who may (?) be more likely to take a dim view of stepping outside gender role. Why take that risk?
Probably massive row internally if looked like going ahead as plenty of Tory women are outspoken and no nonsense types. The sort of women you really think twice before fucking with. Why risk that when. This is not an issue they give a toss about?
It is imo an error to think Tories are on side of women here. Neutral I'd say.
And at the moment. Neutral looks insanely positive next to all the other parties on this. Who are broadcasting that they don't GAF about women and girls through a huge speaker system at full volume, 24/7.
