Just that really
I remember when this whole madness started and various bearded men in skirts in women's refuges were so clear that women needed to expand their definition of women to include them....
I've always thought men need to become more involved, even just thinking about it and that the solution is for men to expand their concept of what being a man is....
But then I'm an old-fashioned feminist who has always seen performing gender-roles as an issue!!
