Absence of evidence is not the same as evidence of absence.
To obtain evidence, you would need to look very carefully. Until very recently, most men using women’s spaces were “transsexual” and very rare.
So if there was an increase in attacks on women, it would be small and thus difficult to assess statistically.
Most women would not report negative experiences.
Many places may not record the sex of the assailant. The police certainly do not.
Their campaign has been deliberately set up so that it is nigh on impossible to obtain evidence.
Why would that be, do you think?
Imagine if there really was no increased risk to women, and trans campaigners truly believed it. They would want to prove to women there was no increased risk, wouldn’t they? So they would have asked for transparency.
If police had recorded sex and chosen gender for all cases, we would, by now, have reliable figures, giving us a comprehensive picture of rates of criminal offending.
They chose to do the exact opposite. It’s pretty obvious why.
