Fantastic.
My language is having grammatical genders, and it always was:
die Sonne (she/female)
der Mond (he/male),
so I would immediately run into the wrong lavatory at this restaurant…
also:
der Stern (he/male):
either your vague theory „prooves“ that the VMS has no German or other origins, coming exclusive from a latin understanding,
or the thin-iced idea of women „representing“ the stars (which come either combined with each womens‘ figure, what kind of representation may that be? Or women are just seen bathing, without any reasonable astroXoXical relation) is not to be kept upright anymore.

By the way, I agree with you that there are nearly no original(!) male figures, apart from those in Sagittarius and Gemini badges, in whole VMS.
