Eden

Just curious, have you read the final book? Some of the same issues you bring up are addressed in the final book, such as the disturbing relationship between the wizards and non-wizards. Although much of clearly runs parallel to the spiral of systematic racism and dangerous ideals of WW2, it does address that issue very plainly. Snape's worst memory is also given a bit more of a justification. Not that it would or should change your opinion on the series, I just thought it would be interesting fodder for discussion.
