Yeah, but the correct reply is "I'm just not into you right now, if that changes I'll tell you and you tell me if you've moved on yet", not "You and the guy who threatened to rape-murder you should carry torches for me and I'll pick the one I like best when I hit puberty". Hermione is feeling betrayed because she's not special enough to Harry, telling her that she's only special because of her gender won't help matters.
