The apparent mass murderer, instead of being the stereotypical "jihadist," turns out to be fanatically anti-Muslim and ardently pro-Israel. Indeed, he was much influenced by such neocons as Daniel Pipes. The children he massacred had held a pro-Palestinian rally the day before, and the Norwegian government planned to recognize Palestine and get out of Libya, both acts eliciting the hatred of neocons. As to his religion, he is not exactly a follower of the Prince of Peace, though he may be some sort of Christian rightist or theocon. That is how, as a hater and a killer, he could describe himself as a Christian and a conservative. He's a sort of Hageeite. (Thanks to Ralph Raico and Gary North)

UPDATE from Ralph Raico:
Few of the reports I've seen mention the gentleman's partiality to the State of Israel.
