It brings out the worst in me. I can tolerate anything (well almost) except intolerance. I've seen JK Rowling speak several times now. One point that she made quite strongly is that she gets letters from time to time from people who assume that:
a) she believes in magic - she doesn't (every now and then she comes across someone who gives her a knowing look and asks about ingredients for spells - she tells them very clearly that IT IS ALL MADE UP)
b) she thinks that boarding schools are a good thing - she doesn't, it is just that children are not allowed to have adventures in the real world (I've mentioned this before). They are barely allowed to cross the street without an adult.

By the way Helen, if you find Hermione at all unsympathetic it may be because she is based on the author, who describes herself as a bookworm at school. Hermione may have her head in a book but she is not a sneak and she does get better as the books go on, honest!
