Whilst I appreciate that you tackle the detail of these things, I think you're being naive.
Six women's groups that I belong to who are trying to organise a cohesive objection to this ideology, most of it simply asking questions, have been continuously shut down by the online provider because of transactivism.
Women are writing to MPs, through the correct channels, and being sent form letters back completely ignoring all the points they are making.
Women are being doxxed online and threatened for speaking out.
Most people have no idea about any of this. Why do you think that is?
In terms of exceptions, and opt outs, they are simply ignored. Otherwise you wouldn't had transwomen raping the female inhabitants of a prison.
A swimming pool in Yorkshire shut down the ladies only session last week because they are completely unaware of the legality of any of this. Because no one is telling them!
The only reason they took legal advice is because 6000 people signed a petition.
So I can neither share your confidence in people understanding the law, and I profoundly disagree that any women are being listened to.
