The way that it impacts on our safety is that prior to female people being told, through media, peers and direct signage on toilet doors and at basins etc, that male people have a right to use female single sex spaces too, female people had a range of options available for their safety.
This included walking out, pointing out they were in the wrong toilet, importantly, alerting other female people of the presence of that male person either while in the toilet space or at the door. Also we were inclined to get security or call the police.
These options are now clouded in indecision. There are some toilets that even have signs that say to female users that microagressions are hateful. Meaning even looking at a male person to assess their sex can be considered hateful by the organisations who have those signs.
That is the very real impact on safety.
So to, it gives legitimacy, not just normalisation, to male people being in that space. Including those who wish female people harm in any way. This also includes male people who simply wish to intimidate female people with their presence. After all, single sex spaces are there to provide female people space away from male people. All male people above the age of about 8 years old.
The sex crime stats posted numerous times on this thread show that for safeguarding risk assessment, male people who have declared they are transgender, have at least the same risk as all other male people in the UK.
So, please can you explain why you believe that they should be exempt from safeguarding decisions? Such as excluding them from female toilets?
Excluding all male people has been done for proven reasons. Looking at those statistics, can you tell us why those statistics don't show that that group of male people still need to be excluded just like all the rest?
