OP, there ARE many conversations that are happening using language that is suited for the audience though. Women have been doing this already for years and will continue to do so.
Don’t forget women are speaking in parliament, they are speaking at committee hearings, they are speaking in debates (where those can be had) and are speaking on panels.
It is patronising to explicitly or implicitly tell women that we are not doing this. It really is.
We are now just speaking other ways too. Because after years of speaking in the way you advocate "You catch more flies with honey than with vinegar.", we have been ignored, spoken over by either males or by women telling us we are doing it wrong, by politicians and by policy makers.
The work to prioritise sex based rights for females over gender where it matters is happening using a multitude of different ways, with different approaches and different methods. It needs to reach a wide diverse audience and is now doing that.
Don’t forget, for every person who sees the bluntness as problematic, there are multiple people who go and find out more information. Or who mention their discomfort of the bluntness to someone who then explains what has been allowed to happen and does it in a ‘reasonable’ way.
I suspect it is people who think in polarised, absolutist ways who will remain polarised on this issue. And to clarify, I don’t mean the women saying ‘no’ to male people accessing female single sex spaces are polarised. I mean the people who see women saying no to those male people who then believe those women are the ‘enemy’ or ‘Nazis’ or ‘far right aligned’!
And those polarised thinkers are not going to change. I consider them a small group though.
The ‘hard line’ has moved because we now realise that those cannot be compromised on while still protecting the women and children it needs to protect. There are no compromises on that.
As to ‘compromising’ on language used, there is no need. Those ‘compromises’ really are still happening everywhere. As they have been for years. Telling us to do so is like telling granny to suck eggs and that never fucking goes down well.
