из серии "не может быть!"

ни мужчин ни женщин - это "неприлично". дальше - простенький английский:
The famed Ivy League institution rolled out a series of gender-neutral terms aimed at removing the word “man” and other male-leaning language from official school material.

The word “actress” should be replaced by “actor.”
A “cameraman” must now be called a “camera operator.”
There will be no more references to a “cleaning lady,” but instead an “office cleaner.”
New students are no longer “freshmen” but rather “first-year students.”
A “mailman” no longer delivers letters or packages, because that’s the work now of a “mail carrier,” “letter carrier” or “postal worker.”
Nothing is to ever be done for the betterment of “mankind” but instead for “humanity,” “human kind” or simply “people.”
A “waiter” or “waitress” will no longer dish out grub, as that’s now the work of a “server.”
An “average man” is now an “average person” or “ordinary person.”
