I don’t know that there is a deity with historical ties to watching over queer folks, but I would say that most Kemetics would probably first think of either Set or Neith as their first associations with this. This is because Set is about boundary breaking, and is technically queer himself, and because Neith (iirc) is hinted at being androgynous, being of two genders or intersex.
Anyone else have any deities for anon?
Hapi is a personal deity that I think of when I think of gender non-conforming
