Hamas - like most terrorist ideologues - put forward a big game about the purity of their organisation, and that's enforced pretty hard at low to mid level. But once you get to the old bastards who might have had coffee with Yasser Arafat and Ariel Sharon or Yhitzik Rabin the values tend to be much more fluid about who they use and accept. Because they didn't get old in this game by not breaking the rules whenever it was expedient to do so and have a back pocket full of flowery bullshit to baffle their unwashed masses with to justify it.Just so we are all clear. You think a gay Palestinian could be part of Hamas
Now I consider it unlikely a gay Palestinian man would work for Hamas unless his family or people he cared about were under direct threat of violence; but Mossad would not be doing their job if they didn't at least ask some token questions.
