Which university ? Cologne was the biggest (measured by number of students when I last checked) and there was none of that nonsense when I attended. Well, very little of that nonsense concentrated on a handful of nuts who cut off their dreads because they read about "cultural appropriation" in some blog. Charitable people indulged them for five minutes and sought someone else to talk to, less charitable people said something like "Ah, uhm, OK" and talked to someone else.
Naming the university is giving away a bit too much about my identity to be honest, so let's have a look at Cologne instead. After looking around a bit on the internet, I've found this
official guide for gender-neutral language. It goes pretty deep into gender specific language if you consider that it's an official document by the university. Among other things, it states that „Der Verfasser des Werkes ist unbekannt.“ is not okay, because it is gender-specific, and it tells students that they should think about the ways in which they use gendered language, and then has a list of words attached to it that includes things like "Staatsmännisch", "Manneskraft", "Meisterschaft" and tells students that they should avoid them because they reflect traditional gender roles and gender stereotypes.
That's again the official guide. It's relatively harmless in that it does not tell people to use any "creative" ways to un-gender words and instead just advocates for vigilance in how you speak, but the attitude is already there as a general guide for everyone, so why would I assume that it does not translate into more extreme versions in the people who visit social justice related courses?
I did not find any evidence of that specifically for the University of Cologne, but
here's something that was released by the "AG Feministisch Sprachhandeln" of the Humboldt-Universität, Berlin (which has 32,553 students according to wikipedia).
Among other things, it does have a list with certain "creative ways" to write gender neutral on page 13, which lists the Studierx, the Studier*, and Studier**, which apparently is the plural of Studier*. That I actually admire, just adding an extra * behind the first one to show the plural is rather clever.
On page 17, it gives the following example sentence:
Dix Studierx hat in xs Vortrag darauf aufmerksam gemacht, dass es unglaublich ist, wie die Universität strukturiert ist, dass es nur so wenige Schwarze/PoC Professxs gibt.
So yeah. That nonsense will of course never leave the campus.
