the idea that Medusa was raped and then punished for it, and if what Kevenn said is correct, then this was never even frowned upon!

Hoo boy, yeah. Ever read Ovid's Metamorphoses? That thing has more rape in it than a whole shelf of hentai. Sometimes gods will protect women from something like that, sometimes...eh. Athena may have been the wisest deity in the Greek pantheon, but the writers of the myths She appeared in were still ancient Greeks, so it doesn't surprise me that the same people who wrote about a whole gang of rapist gods did not do a 180 and write Her as a feminist.
