Tough.
Transgender women and men know they are. So do their physicians.
Not necessarily. Also, this scenario relies on people volunteering the information that they are trans upfront. To be truly sure, you would need to check the medical history of every woman who comes in to the shelter. Is that something you'd support?
If they don't have enough foresight/brains/whatever to bring a phone number for the shelter owner to check, then there is something very wrong with their claim.
Wow. A woman fleeing abuse and looking for shelter should have the "foresight/brains/whatever" to bring a phone number for their physician - who may not even be available or have the required information - in order to qualify for that shelter's protection. Sounds like a great idea.
Women come to shelters hoping to be protected from predatory and abusive males.
So do trans women. So why are you putting barriers in their way?
Part of those checks and balances you speak of would be...making certain that the man claiming to be transgender really is transgender.
Except, as said before, the individual is under no requirement whatsoever to volunteer that information if they don't want to, and medical histories are personal and private information, so the only way to be sure would be to run a medical history check on every woman who comes to the shelter, regardless of whether or not they claim they are transgender.
You will notice, I hope, that I'm not saying that transgender men-women should not be admitted to such shelters at all.....just that they prove that they are. That's sheer common sense. Face it; political correctness aside, the odds are FAR greater than some predator male is lying to get to his 'woman' than that, just coincidentally, a transgender male-female just happens to need care.
And thus, your transphobia is exposed. You seriously believe that it is FAR more likely that a transgender person is just a "predator male" than a genuine victim of abuse. That's just plain bigotry, and not borne out by reality at all, even remotely. I would like you to provide one shred of evidence than that is the case.
So use your head. Check the probabilities. Make the transgender support his/her claim. THEN let him/her in.
Unfortunately, the world isn't so childishly simple, and "probabilities" doesn't even enter into it. You're just basing your presumption on nothing but your blind bigotry against trans women, and the completely baseless and unfounded assumption that a trans woman is somehow more likely be a predator than someone who claims not to be trans.
Your solution simply doesn't work. All it takes is for a trans person to not disclose that they are trans (something that should be well within their rights) and your system utterly breaks down. What's more, this "solution" isn't really a solution at all, because there is no actual problem to be solved. Nobody has demonstrated that there is any significant number of predators posing as trans women to gain access to shelters. You're inventing a problem borne out of bigotry and blind prejudice, treating trans women as fundamentally less than women.
Because it's not really about the safety of women. It's about putting trans women in their place.
