Was going to respond to the first Shades of Gray thread but it appears to have gotten infected by spoilers.
Disclaimer:
Not a Rowling scholar, I. I've read the books about twice.
I find the particular combination of boarding school lit and
poorly-conceived modern-setting middlebrow fantasy too juvenile to be
worth the obsession so many are exhibiting.
Anyway, none of the characters cited here are particularly good,
nor particularly evil, and I think that Harry recognizes that even when
they get in his way. It's a trinary system - there's good (people
that help Harry), there's bad (the people who ultimately are interested
in killing Harry and/or the other good guys), and then there's the
forces of stupid.
That's what I get out of these books. The
people who have chosen sides are the ones who know what time it is, and
then there's everyone else. It's amusing that "muggles" was the
epithet chosen for those who are unconnected to the reality of
Rowling's magical society, when so much of that society allows
its perceptions to be so massively muddled, by their own trivial
fascinations with their powers or by those who think the public good
lies in bureaucracy and obfuscation.
Now... I'm willing to admit
that my reading of Harry Potter is massively influenced by my
politics. I don't see the real world playing out in the same way,
and I'm sure that Ms. Rowling would be writing out of an English/UK
context, but the notion that large chunks of the population are
willingly disconnecting themselves from a functional grasp of
reality... well, that rings pretty true.
My point, though, is that incompetence is not the equivalent of moral complexity. Neon puce is not a shade of gray.
