Still not getting where you get the impression that the Amazons don't hunt and fish for their meat, especially considering that one of their main Goddesses is Artemis and they don't have a lot of childbirth going on. This is a culture where the Hunt is a vital part of their way of life. A Goddess of the Hunt wouldn't be that important to a culture where hunting isn't neccessary. And, if Artemis gives you a stag, one of her most sacred animals, well... There's a lot of myth tied to the Stag and his relationship with the Nature Goddess that even worked it's way into Christianity.
And, there's a big difference between knowing where your meat comes from and facing, for the first time, that cute widdle deer looking at you with it's doe eyes. Boars aren't nearly as cute. They're not cute, at all. Not surprising to me that a young teen girl would falter, there.
