Sorry for commenting (I know its off-topic) but I find it quite interesting,
Brummbaer. So why do think that English isn't gendered? I would think that the knowledge of grammatical genders actually is a question of education, but not a question of language. Of course also German kids have to learn which rivers are female and which are male entities (rivers that were named by germanic, slavic or celtic tribes usually are female (out of religious reasons), the Romans usually gave male names).
Well, I said 'generally' and 'gramatically'. It's a matter of degree. Of course there are words for gendered roles 'priest'/'priestess' (Priest/Priesterin), but they're not declined as masculine, feminine or neutral (der, die, das) but just as the definite object 'the' or indefinite 'a' . Historically probably male roles, like a minister of state were only male, whereas German can easily add 'in' (Minister/Ministerin). But, in German you get der & die Azubi depending on the gender of the person. We have a female 'Home Secretary', but would probably refer to 'she', or maybe 'they' if I really wanted to be non-binary, whilst using the generic title; German has der Innenminister, but might go for die Innenministerin in some/most publications. Some might consider the 'in' non-PC.
This is an extremely simplistic view since English has Germanic roots, but also includes French, Indian, Spanish, Italian, Latin, Greek, Danish, Norse, etc. depending where the inhabitants travelled/invaded/were invaded. I understand some bits of Dutch/Plattdeutsch even sound like English dialect. Even that derogatory Anglo-Saxon word (f***) has Dutch roots.
So, I can see 'DJ' getting a feminine 'DJane' - even as an empowering feminist viewpoint to identify the contribution of women at some historical point, but some might now consider that non-PC. Personally I quite like it, but maybe I'm no longer keeping on top of cultural changes.
It's complicated - especially with many countries using variants of British English in former colonies. You can't win; you can't change the rules; you can't get out of the game. To someone, somewhere, you'll always be wrong - even to other, native, English speakers.
