It doesn't need any bending to make Islam look bad. I've said before, supposed "Chrisitans" who blow up abortion clinics cannot point anywhere in the Bible to support their arguments. Muslims who slaughter innocent people CAN point to somewhere in the Koran (Quran, whichever, alternate spellings I've seen), to support their arguments.
And regarding Jesus: Knowledge of how the Roman system of law and culture worked, would prevent any speculation that Jesus was switched with a guard (or that the guards were "asleep at their posts" allowing someone to steal Jesus' body, or that he wasn't dead on the cross, etc.) All secular and religious history clearly points to the fact that he died on the cross, and was resurrected on the 3rd day in direct fulfillment of the Messianic prophecy. His words ring true, that He is the only way to God. Not through my actions, not through anything else, only through His sacrifice.
