I'm half annoyed that you aren't in my honors class, because when we all announced our thesis topics, at least two people asked how mine could possibly be arguable. (Haven't worked out their 'shipping preferences yet. Will laugh if they 'ship conflicting pairings.)

Yes, I know Harry mostly ignores Ginny during the series. I'm taking that as supporting evidence for Harry/Ginny, actually. Harry's known Hermione for most of six years, more than three of which were after he first started being attracted to girls. If he were going to discover a romantic attraction to Hermione, I think it would have happened by now. And Ron and Hermione are definitely showing signs of being attracted to each other, so even if Harry does find himself falling for Hermione, it won't be Harry/Hermione, because Harry wouldn't hurt Ron like that.

By contrast, Harry's really known Ginny starting at the beginning of OotP when she started talking in his presence. It's only a little more than twelve months later when he starts realizing he likes having her around, and for most of those twelve months, he was both crushing on Cho and having Voldemort flitting in and out of his head screwing with his mental equilibrium, so really it's probably about two months between realizing she exists and realizing she's attractive. This seems like a much more logical time scale.

And True Love a la Disney is not love in a lot of cases, it's lust and (usually) wedding bells. Cinderella, Snow White, Aladdin, Pocahontas, Atlantis...

Little Mermaid and Beauty and the Beast are the only ones popping to mind in which the romantic leads are shown falling in love. Sleeping Beauty, maybe, we know they were dreaming of each other but not what the dreams consisted of. Robin Hood, they're already in love. Not quite sure what to make of Lion King, honestly...okay, now I'm rambling.
