I have no hatred for Israel, the Israeli people, the Jewish people or the practitioners of Judaism. I do, and will, however, condemn the repeated actions of the Israel government, and militaries, who are the ones that create the opportunities for these extremists you speak of. Why do you think Hamas is gaining power among the Palestinians? Because they are desperate.
As for that theologian... Well, looking at the reactions from the reporter, I think he was a bit more zealous than they would have expected. However, note what he said by the end, "We hope that they will both reach the shores, and become martyrs." Are you sure we aren't misinterpreting martyr here (Might also be something lost in translation)? Martyr doesn't neccesarily mean you get killed in the name of Allah, you know. In a way, the 599 unharmed people from the convoys still in Israel are martyrs, even if they're still alive and well. They did (presumably) choose to stay of their free will.
