Steve points me this post, Observations on Arabs. The author, an anthropologist by training, has 12 of them. Interesting, even if you don't agree with all of them.
Update: speaking of "cultural differences," see below (hint: Wonder Woman + pole dancing + lots of guys with palsy [Uberbrown responds]):
I await the headline, "brown actor breaks his kneck trying to be expressive with dance." Is is me or do brown guys dancing joyously in unison seem kind of "gay."
