If a group of male people feel unsafe in the male single sex provisions in the UK, the answer is not to allow them into the female provisions where they can cause distress and harm to female people.
If a group of male people feel unsafe, then there are other options.
For instance they should do what the female people with transgender identities in the UK who take testosterone do and work together to communicate where alternative solutions are so that they can plan their trips away from their own home. We know female people with transgender identities who take testosterone do this, they tell us on threads on this very board.
I would certainly recommend that a public campaign to make male single sex spaces safer for ALL male people is commissioned by as many organisations as it takes to make achieve safety. If safety in male single sex toilets was such an issue at this time, where is this public campaign? There would be funding from many sources to make this happen.
Also, where are the statistics that support the additional safeguarding measure to create a special space just for this group of male people away from all other just as vulnerable male people and all other male people.
The statistics for this sub group of male people, those with transgender identities, show clearly that they are still being convicted for sex and violent crime at a rate that can be said to be at least that of the general male population of the UK.
There are NO statistics that show that this sub group of male people commit sex and violent crime that is less than that of the general population of female people in the UK. But it is, to be blunt, irrelevant because female people need to have, and it is a human right to have, privacy and dignity away from male people. All male people when needed, and toileting is one of those instances.
Pleas for women to be concerned about where any male person who rejects the single sex space that organisations have provided as per the expectations under human rights provisions is really just adding to the burden of female people. This was always an issue for male people to sort out.
