This story is the result of two widely accepted proposals:
-Transwomen belong in women's spaces. -The only moral response to someone coming out as trans is to affirm their new identity.
If you agree with both proposals, and many people do, that means in practice you believe one transgender woman is worth >99 cisgender women. No one says that out loud, but prioritizing victimhood means that's the calculus they deal in. Adding more exceptions to problematic examples like this one doesn't address the root problem with that hierarchy of values.
If we want to have this discussion, please provide some actual data about the rate trans women sexually assault women in women's prisons.
There is also no data whatsoever indicating that if a man calls himself a woman, then he poses any less risk to women than other men.
I agree that prisons need to stay sex-segregated, or revert back to being so where authorities have made this abominable ideological error of incarcerating men in the women's prisons.
What asymmetry is that? I provided a statistic for the abuse trans women currently suffer in the system, but no one else has provided anything but anecdotes and appeals to some sort of common sense. It, and correct me if I'm wrong, feels like you're giving a similar sort of special reverence to cis women who suffer sexual assault than trans.
To be clear, I think sexual assault is bad all around and I hate the idea of abusers slipping being enabled, but it's somehow acceptable that many many trans women are abused instead of the potential for even one more cis woman to be sexually abused in prison than there already are (let's not kid ourselves here, scads of abuse already happens).
I guess the answer to this particular trolley problem for many people is to not even consider pulling the lever because it's 5 trans women but one cis.
