Good of you to apologize for any hard feelings, but it is certainly one way of reading the conversations Kaliyo has. Whatever interpretation one puts on why she says it, Kaliyo certainly seems to indicate that lovers could be of either gender, which at least acknowleges that same-sex affection is by no means an unheard of occurence in the Galaxy Far, Far Away. So I think whatever the character herself is or is not, Kaliyo is totally germane to the SGR discussion.
Yes, yes, it could still be that she's just that manipulative, is totally straight and not into women at all aside from being willing to sleep with them and make them fall in love with her, but that seems like reaching and I'm not sure why the reach. Why not just go with Occam's Razor, in this case the simplest explanation being that she's bisexual.
