And still, no one can give an answer which doesn't require faith, and is accepted upon by all.
Truth should be something that actually happened, which in this case, it has not. There were no incidents of Christians going out beating up Jews.
In fact, in the movie, it is pretty obvious that it was both the politics of the Romans and the politics of the Jewish leaders that combined to end in the death of Jesus. If you have ever done the Stations of the Cross (don't know if you're Catholic or not), you'll know that they usually depict with Romans soldiers flogging Jesus, standing by the side and watching him fall, etc.
Mel Gibson's movie found both good Jews and good Romans, however, who objected to this being done to an innocent man; and the same is true in the Stations. Veronica, who comes forward to wipe the face of Jesus, is a Jew, moved to pity by this torture. Simon of Cyrene is a Jew, forced to carry the Cross by the Romans.
Hence, the liberals are not telling the truth, and there is no question about it. But for them, truth is what they say it is and what serves their ideology, objective reality be damned.
