I don’t suppose a trans woman would be much of a threat to me trisher but a man who had deliberately positioned himself in a place where women are vulnerable might well be.
As a woman I carry out, almost unconsciously, frequent checks upon my safety. Should I take this shortcut in an alley, does the underpass or the crossing the busy road carry the most risk, should I stay at the get-together till it’s dark, do I go for a walk along footpaths in fields.
I make choices based on the likelihood of male violence. So anything that gives men access to what have formerly been relatively safe places for women needs to be questioned.
In opening up these places without question or forbidding women the right to question, we have effectively given some men a carte blanche to use women as they will.
