German is a mess right now with regards to "gender" or "sex."
The roots are in the supposedly "Frauenfeindliche Sprache" where so many nouns that refer to professions are masculine gendered words. (But not all, siehe die Lehrkraft).
But the "corrective" action that is being taken, aside corrupting the original language, is going in the wrong direction: it is emphasizing and recommending a MORE BINARY approach, which is not actually more inclusive at all, instead reads rather hetero-normative. Ask any LGBTQ+ person.
I propose the solution is to dial back and start using the words traditionally again, where a masculine gendered word is understood to refer to both sexes (or any sex, or no sex at all, I nod to the LGBTQ+ community).
Finally, I thought that the plural forms of German nouns have no gender at all (even in grammatical constructions), so I don't understand the trouble to which public speakers go, to address both sexes with separate plural words. It does make for some very cumbersome speech.
Below I add a few words where I ask, what is the "feminine" form? I've not heard it yet (as of Sept. 14, 2021):
Der Suchende (e.g. Schutzsuchende)
Die Lehrkraft (instead of der Lehrer!) Can men not be referred to as "die Lehrkraft?" (NO! They would feel so emasculated!)
Der Unternehmer (in recent TV "Trielle" Amin laschet failed to address Unternehmerinnen!)
For a moment I theorized that only nouns ending in "er" are victims of the linguistic gender war (i.e. Lehrerin, Bürgerin, ...), but on dradio.de have noticed Hörer used without a corresponding feminine gender (they do not acknowledge the existence of any Hörerinnen). Or what about Fahrer, like "Busfahrer"? Is there a feminine ever used (Busfahrerin)?
Also, I notice that when such a "personal noun" is part of a compound noun, the effort to include the feminine is abandoned. For example:
Korrespondentennetzwerk. (What of Korrespondentinnennetzwerk?)
I suppose the female(s) cannot be included because the actual noun is "Netzwerk" - which has no female version... but then it also implies there are no female members as part of the "Netzwerk" - how can one reconcile this "sexist" output?
In sum: a mess.
I don't know the solution.
