Personally, as a long-time reader of Archaeology magazine and enthusiastic amateur in the field, what I keep being surprised by is the field's routine assumptions that people before us were somehow stupid.
It derives from the "progressive" view that is taught so thoroughly in most schools (especially colleges and universities) that "new" means "better" and that history is irrevocably moving from worse to better.
Good grief, dude. Not everything has some deep underlying 'message'.
Well, I would agree with you...except, they brought in the author of the 'Vagina Monologues", Eve Ensler, to consult on making the film. You do not bring her in unless you are putting in some deep underlying message which she would approve of. For that matter, Eve Ensler would not have consented to consult on the film unless she agreed with the message.
Don't hit the keys so hard, it hurts.
