Do you deny the existence of women?

You may say now: "Why should I deny the existence of women? I am a woman myself!"
Or: "I am married to a woman - why should I deny her existence?"

But things are not so easy as all that, at least not in Germany and in France.

Time was when one could say: "Teachers and students". In German: "Lehrer und Studenten."
But if you say so now, you "deny the existence of women" - as the saying goes.

You must always use the double form: "Lehrerinnen und Lehrer, Studentinnen und Studenten, etc etc etc". = "Female teachers and male teachers, female students and male students etc etc etc".
And there is no end to it.

So - what do you do? Do you alway use the double forms, so as not to deny the existence of women?
Or do you use the simple form, because any child knows, that there are two sorts of humans, or even more?

By rights you should always use this form: " "Female teachers and male teachers and non-binary teachers, female students and male students and non-binary students etc etc etc".
And there is no end to it.

Time was when it was enough to say: "Donaudampfschifffahrtsgesellschaftskapitän".
Now you must say: "Donaudampfschifffahrtsgesellschaftskapitäninnen and Donaudampfschifffahrtsgesellschaftskapitäne".

I noticed that when there is a positive or a negative idea attached to the words, some use only one form.

Murderers and gardeners should be "Mörderinnen und Mörder, Gärtnerinnen und Gärtner" in German.
But some women prefer to just speak of "Mörder" and "Gärtnerinnen".
