I don't see what the big deal is. I wouldn't even call it an agenda, its genre emulation. Its made to emulate these romantic fantasy novels. That's not an agenda, that's trying to make the game play like certain kinds of books. Would anyone say that Eden has a pro-feminist, pro-pagan agenda because it publishes the Buffy the Vampire Slayer RPG? I've never heard that. Those elements are there, because they're in the Buffy TV Show (by the creator's admission). It doesn't mean that Eden is pushing any such agenda, they are just making an RPG that simulates that genre of fiction. Same thing for Blue Rose.
If you find the egalitarian society led by divinely mandated monarchs to be distasteful, then that's because you don't like the genre. Its like complaining about the Star Wars because you don't think that a bunch of sorcerers and mystics would be considered wise advisors in a sci-fi setting. You should probably play Traveller or something.
