I mean after the GRA has closed? I can't see how the legislation won't get through, unless it gets kicked into the long grass because of Brexit etc... I don't think many people care/know/understand what is going on though it might seem like that to those who are in the thick of it and can hardly think about anything else at the moment.
If it does get through, the next step is 'reforming' the EA. This is where I think things could begin to turn as people realise what the actual implications are for so many parts of our lives.
Longer term, turning points will surely be sport where some women do have power and a stake in resistance and the medicalisation of children. The latter will one day be classed alongside any number of other gruesome medical experiments gone wrong I think.
