I'm sure JKR would be the first person to admit that she was wrong in her choice of words for some answers. Interviews are hard anyway, since you don't get much time to think before you answer- it's mostly on the fly, and if you take too much time thinking over a question, people take note. It looks like she and the whole interview staff have a case of the 'it seemed like a good idea at the time' mentality. Needless to say, the fandom has gone absolutely batshit after all that. In fact, it's still going batshit. People have gone so far as to rewrite book 6 online for Harry/Hermione content, and possible death of Ron- yes, they all hate him that much. Which makes me sad, because I love all the Weasleys =/

(And Right-o captain, we'll pretend I never said anything concerning that glowing orb of evil!)
