Co-ed to parents: my roommate has a dick

Daniella Greenbaum writes in WSJ about Mount Holyoke College, the liberal arts college for women in Massachusetts:

Mount Holyoke will accept applications from anyone on the gender spectrum — except those who were born male and still identify as male. In other words: men.
...
But [Ms. Pasquarella] said students can’t indicate in advance their preferences regarding a roommate’s gender identity. That would be discriminatory. The school wouldn’t consider such a request, she said, “the same way we wouldn’t take into account the request of someone who said, ‘I don’t want to live with a black person.’”

Presumably, then, Mount Holyoke would admit a person who was "born male, but does not still identify as male," but, if you are a young woman, you would not be able to request that you not be assigned said person as a roommate.

Gee, parents are going to be really happy with that one: freshman girl texts mom and dad: "I just unpacked and my roommate is walking around the room with a bra on and his - er, her?? - dick and balls hanging out. Gag me with a spoon!"

It is also interesting to note the circumlocutions we need to go through these days to identify the gender of people. Instead of calling them simply "men," we must resort to expressions like "those who were born male and still identify as male; in other words, men." (I'm still not really sure about that one. Do they mean, like, for reals men?) If I say "freshman girl" instead of "person who was born with a vagina and still identifies as a female and who is in her first year of college," is it a micro-aggresion?

I also note that the phrase in the WSJ article "[persons who are] born male and still identify as male" implies that it is possible to switch the way one gender-identifies. That is, if there is a time when one still identifies as a male, that implies that there may come a later time when one no longer identifies as a male. The WSJ article provides an example of this very phenomenon:

Mount Holyoke President Lynn Pasquerella, when I asked her how the school is navigating these gender cross-currents, told me a story. A young Muslim woman attending Mount Holyoke was assigned a dormitory roommate who was born female but at some point as they lived together began identifying as male. The Muslim student objected on religious grounds, telling the administration that because she accepted her roommate’s chosen male identity, she could no longer live in their room comfortably. Ms. Pasquerella said the school resolved the matter by separating the students — a result that satisfied both parties.

That is, the roommate was born female and identified as a female for most of her life, but "began identifying as male at some point."

But, if it is possible for a woman to begin identifying as male at some point, isn't it also possible for that woman to stop identifying as male at some later point? Conversely, if it is possible for a man to begin identifying as female at some point, isn't it also possible for that man to stop identifying as a female at some later point? And what implications does that have for the young woman who might be forcibly assigned the born-male-but-no-longer-identifies-as-such as a roommate? The born-male-but-no-longer-identifies-as-such obviously stopped identifying as male at some point. But, such a switch implies that it is possible for him (her?) to start identifying once again as male at some later point. And what if he (she?) does so in the middle of the night in the dark as his (her?) roommate sleeps in the bed next to him (her)? Cetera quis nescit?

It is astonishing that universities will pass a myriad of regulations to prevent young men from raping women, but, apparently, will resist taking simple common sense steps to separate young men whose gender identification has been inconstant over time from sleeping in the same room with young female roommates. Of course, exactly the same logic applies if we are talking about allowing men who (currently) gender-identify as women to use women's lavatories. If your young daughter has just walked into the women's lavatory in the park, it is quite possible that this may be the very moment at which a man who gender identifies as a woman may also walk into the lavatory and start to gender-identify as a man again, with potentially highly undesirable consequences for your daughter.
