From the POV of how it weakens Christians, it makes sense when they say that Christianity is a Jewish-made 'religion'. Nobody denies that it is Abrahamic. It accepts the Old Testament, which is highly contradictory to the New one. Nobody can deny that all those involved had Jewish DNA (The 'Holy Mother' etc). Nobody can deny that he willingly went forward, allowing them, giving them, the power to crucify him, God incarnate. The Jews killed the King of the Jews, INRI. Then James, The Just, Jesus' brother headed up the family dynasty. You can't really deny that the Church is ZOG. All of that being said makes for a losing, dented people who have very little in the way of victory on their side.
On the other hand, nobody ever nailed up a willing Odin or Thor to a cross. They'd fight you to the death. If I were looking to subvert a people, I would much rather they go with 'turn the other cheek, otherwise you won't get to heaven' mentality. So much easier that way.
