So, if I understand this right, and Creasy did really not consult with women's groups (?) but with stonewall.... that speaks for itself, really.
This is either some part of the larger attempt to redefine 'woman' (like in Scotland fairplayforwomen.com/scottish_stole_woman/), or just an easy way to gather browny points with voters and the stonewall crowd.
Then the Green Party Scandal hit, which gave the whole wider issue of self-ID and safe guarding a disturbing 'some furries wear nappies, get over it'-spin. It was so disturbing, indeed, that as a consequence Caroline Lucas even talked about meeting one of those unspeakable women's groups.
And suddenly it hit Stella: that a misogyny law without input of any women's group might not be a good look if the winds, indeed, change- in this potentially new climate, that apparently doesn't generally equate women with boundaries summarily to the KKK anymore.
Time was short, and the easiest way to check the 'dialogue with women box' - without any hazzle that might alienate stonewall - was going on mumsnet the day before D-day.
