I find the whole "Love Potion" theory utterly ridiculous. I believe in a D/G attraction and am a fan of the Snape/Lily/James - Draco/Ginny/Harry love triangles, but I can't buy this.

First of all, you think too far. It's like you're trying to decode a secret message. JKR wites these books for entertainment, and if she were to write things that way and expect us to figure out a different meaning for everything that is said, people wouldn't buy those books.

Second, Hermione would not do that, no matter what. It is stated that she doesn't think love potions are dark or dangerous, but she still has a good judgement and knows love can't be created that way. She wouldn't risk hurting both Harry (when he would find out that he was being dosed) and Ginny (when she would find out that Harry wasn't really attracted to her). If she was happy when Harry and Ginny got together, it is because she was a friend of Ginny's and knew that they were right for each other.

Finally, I don't know why people have so much trouble accepting it, but Harry did love Ginny, or at least like her, perfectly naturally. IMO, he began to be attracted to her in book 5, when she finally started to be more herself. But he was struggling with loads of different feelings, including his fading attraction to Cho and the loss of Sirius. Early on in book 6 we start to see a developping relationship between Harry and Ginny, like when he feels annoyed that she spends time with her other friends or laughs at her jokes. I believe that Harry liked Ginny totally honestly.

Thus, I do not deny that there may be some attraction between Ginny and Draco. Especially coming from the latter. it is not impossible that they both like Ginny and that she dates Harry because she thinks Malfoy hates her. However, I don't believe in the "love Potion" thing.
