Forgive my ignorance, but it seems that there is more information in the "explicitly inclusive" form than the "implicitly inclusive" one. Doesn't the existence of the inclusive form allow you to explicitly use a non-inclusive form? So in this case

Lehrer being explicitly male and Lehrer:innen being explicitly inclusive?

I appreciate that this seems to be an emotional topic, but if people choose to use language in a new way, would it not be best to not withhold that information from you as a reader? Someone else wrote that it's like using an ad-blocker, but if I were to read an article, I would want to read it in the exact form someone wrote it, no? It's a bit like Americans auto-replacing "fucking" with "f***g" in their browsers to avoid an annoyance, but they lose information in the process.

As a German, you don’t really loose any information. it was introduced somewhere in the 2020s and is not (yet) standardized - and probably wont be.

We Germans know that the generic masculine includes both genders by default. It’s how we use the language.
