Obviously you will not deny that male sex criminals seek to get into women's prisons.
Of course I do not deny actual cases exist of male sex criminals wanting to get into women's prisons. The few that have happened are well documented. As you say they are "male sex criminals" who pretend to be transgender in order to gain access to women's spaces, to continue their crimes.
They're just like many other sorts of criminals. shoplifters pretending to be shoppers, pickpockets pretending to be commuters, scammers pretending to be lonely people in search of love, 'kind' priests abusing minors, meter readers/charity collectors to commit robbery, etc. Practically every sort of crime is committed under some pretence or other.
Criminals do that. They pretend to be what they're not to exploit the weakness of society to commit their crimes.
We don't deny that the vast majority of commuters are genuine, or that the vast majority of shoppers are genuine, that meter readers/charity collectors are genuine, or assume priests are safe around children, etc.
But that is no excuse to deny that transgenders are genuine, that intersex babies are being born all the time, and that intersex people exist, and that some of them have been assigned the wrong label on their birth certificate, giving rise to some of them adopting a different gender.
You still insist on conflating criminals with transgenders to camouflage and justify your bigotry.
You could stop doing that very easily by accepting that intersex people exist, (medical science proves it|) and accept that the vast majority of transgenders are genuine, honest people, not the criminals that you persist in conflating them with.
But your religiously inspired belief prevents you from accepting that sex is not binary or that transgenders exist, based on being assigned the wrong label at birth.
