Herminone is the weird one. Her family aren't witches but she knows too much inside info. She should be as clueless as Harry. It's illogical.
I suspect JK is a closet Libertarian but she'll have to play a liberal to keep her celebrity status. She owes her fortune to the media that hates Christianity. When they picked the Cathedral to film Hogwarts, the media in England and the US did story after story about the neanderthal Christian church being up in arms and howling in protest. They claimed the uneducated rabble would descend on filming with pitchforks, flaming torches and drooling mouths.
In reality, one protester showed up. The media was so disappointed. Their boogeyman didn't cooperate.
Hermione reads books for fun. Harry doesn't. That's all there is to it. As Hermione points out time and again.
Mmmm... yes and no. Harry Potter became famous via word of mouth from children to children. At first, J.K. could barely get it published since most publishers told her no child would read a book that complex and long. But once it did get published, children ate it up. The media, as usual, was an also-ran, looking for a story, and came in well after the fact. The media doesn't have a single creative idea now days.
