Interesting questions, Purgatory.
Part of the problem I see, even if research is done, is that there are still relatively few men claiming they are women and using that claim to gain access to women’s spaces. In addition, many women never report sexual assault when it occurs, for various reasons. Even if predatory males abuse the privilege of being allowed to use opposite sex spaces (which by their nature, they will) the number of reported assaults are likely to be small enough to mean that it will take a long time to collect enough information to prove the change is statistically significant.
Of course, some misogynists argue that if it takes ages to prove statistically that allowing males in women’s spaces increases harm to women, then those harms are barely worth mentioning, ergo women should put up with it. But of course to the individual women affected, the harm is hugely significant.
And that, of course, is if you only count active physical harms. If you look at psychological harm… well Robin strongly implied that a male voice on a telephone line in a domestic violence shelter would be inappropriate, presumably on the grounds that would likely be harmful. And yet there are men who claim they are women now in many such spaces, both on the staff and claiming they are victims. Perhaps Robin can confirm a belief that those males are acting inappropriately?
From the article:
A better solution would have been to “reverse engineer” data on biological sex where it is genuinely needed by using the gender identity question to reverse the answer to the sex question for those individuals who answered yes to the question on gender identity.
This would only work if you were certain that all transitioners reliably recorded their “gender identity” when asked if they were male or female. Many might well record their sex as that is what the question traditionally required.
Instead, the legal intervention midway through the process left the results of the census in a muddle.
Nonsense. Those who chose to muddy the waters on the sex question when designing the census, who also chose to deliberately withhold the information that they were doing so, created the mess. Suggesting that a properly carried out, successful legal challenge created the “muddle” is about as ridiculous as it gets.
