OK, I'm no expert and I'm probably going to get egg on my face, but the way it was explained to me, if they're sunni they can't be wahhabi. To a wahhabi a sunni is kafir. At least that's what I was told by a sunni member of hamas when he was explaining the sects to me (during a prolonged futile attempt to convert me). This was a year or so before 9/11. He (and his fellow hamas friends) really despised wahhabis because of this and their collusion with the British. They were palestinians living in the US. Did they BS me or does the term wahhabi have multiple meanings?
