I also appreciate that you are here debbieinbrimingham engaging with us personally.
Re speaking up, the problem is that if a woman already feels uncomfortable and intimidated because someone is demonstrating that they lack awareness and empathy and adherence to the social norms of good behaviour, be that a bully of any sort, or a male using female spaces, then it is a bit of a red flag in itself and often the last thing it feels wise to do is speak up at that moment.
A lot of us have no expectation at all, that as if by the sheer magic of objecting that the person will suddenly see the error of their ways and start acting reasonably and considerately. It often doesn't work with simple things like asking people to not park across your driveway FFS, never mind women's myriad bad experiences of asking men to stop being sexist or harmful when they are in the midst of doing it.
And as far as trying to assess which males are a risk and which are not, bloody hell its tiring and wearing to have to do that all the time as we do anyway, and we are not mind readers. It is no wonder so many women develop PTSD or become risk averse. Even psychiatrists can get it wrong or be fooled. Often you don't even know a man when you have known them for years but then enter a relationship, or marry and they turn out to be abusive, or not what you thought. Not referencing your situation personally Debbie obviously, I am sure many of us have experienced that and the relationships board shows as much. We become wary of men for good reason not because we are wrongly and ignorantly prejudiced and make stuff up.
Likewise, no one can know whether anyone else is a post op transsexual or not, but have to take their word for it. It is just another way for women as individuals to have to bear the brunt of the difficult and worrying decisions and the risks. I'm so very tired of it.
Totally agree that robust and impersonal safeguarding procedures are the only way to make this work with public situations for women and children as a whole. We should all share in the work of making these tough but protective and caring decisions, including males.
