Seriously, people, what are you proposing here? Some sort of "passing" test, so that only men who manage to satisfy [who?] that they can make themselves look sufficiently feminine have right of entry? Who decides? Do they have to go in front of a panel, while wearing their best make-up? Do they get a photo-ID card they can show to prove they have the right to stay, even if a woman objects? How long is it valid for?
Is there an appeals process, where a man in (imperfect) womanface gets to bring his friends to swear that they'd never have guessed he's a man? Complaints of discrimination in 3... 2... 1...
Most men can be made up to look feminine, with the right resources. Think about Dustin Hoffman in
Tootsie, or Robin Williams in
Mrs Doubtfire, or indeed Antonio Banderas in that cameo in
Paddington in Peru. The same amount of effort has gone into the appearance of the congressperson in question. But when the makeup comes off and the hairpiece is discarded and the beard allowed to grow in a bit and the smart ladies business suit is hung up in the wardrobe, the person reverts to what they really are, a man.
And actually, I didn't have to look too hard to find a picture of him looking pretty masculine, even though he's wearing the hair and the clothes and some makeup.
Do we add to the rules that he's only allowed in the women's bathroom when he's had his hair and makeup done, and is dressed accordingly, or does he still get to go in the day he shows up in jeans and a sweatshirt with three days of stubble?
No, because he shouldn't be there at all. It's an important test case for the very reason that he is presenting such a curated appearance. Because first, that appearance is temporary, just as Dustin Hoffman's and Robin Williams's and Antonio Banderas's appearance as female characters on-screen was temporary. It could be discarded in minutes. But mainly, because he is a man and this is a gross transgression of women's private spaces being forced on women whether they like it or not. And it would create a precedent that would be exploited by every cross-dressing lumberjack on the planet.
Remember, it started out as I just described. Psychiatrists treating cross-dressing men decided it was beneficial for their patients to pretend to be women, and taught them how to do it. They were taught not just to look as feminine as possible, but to behave themselves so as not to make women overtly uncomfortable (allegedly). They were given letters they could show to any authorities who might be called, to prove they had been given permission by their psychiatrists to be there. And we ended up where we are, where any man at all just has to say "I identify as a woman, this person is transphobic and I am the victim of a hate crime" to be allowed to do whatever he wants. Reference the Wii Spa affair.
We have the opportunity to start to reverse this. We definitely should not be conceding the beach-head the moment the first shot has been fired because Dustin Hoffman showed up in full makeup.
