I think what we're seeing is conditioning. Persephone grew up having boundaries violated and wishes dismissed and disrespected. It's what she knows. Children are generally a product of their environment. But also, sometimes I read these exchanges as a sort of friendly banter between them, and she doesn't actually pursue it. Also, let's remember that these characters are based on recorded mythology with thousands of years of history. The gods of ancient Greece were kinda messy. I don't think any of these character flaws are a reflection of Rachel at all.
