Nah, the bold part is correct; Jesus was executed as a political prisoner, not a religious one -- most directly, inciting a riot with the moneychangers episode. Rome didn't care about one more unknown spouting religious philosophies any more than they cared about the practice of Judaism already extant. What Rome cared about was power. And what they dealt with severely was any threat to that power.
All that religious song and dance was appended to the story much later, the aforementioned Saul being a major catalyst (and that guy was batshit crazy, or demented, or both). But make no mistake; if Jesus' notoriety had been limited to the spiritual, Rome's response would have been a gaping yawn. They were interested in the things of this earth: Empire. Period. A religious philosopher was no threat to Rome, nor would it require public humiliation and savage execution. Challenging the power of the Empire, however, would and did bring exactly that response.

Meh, that is supposition that ignores the written history closest to the time period in question, which is a form of modern hubris.
Rome executed Jesus because the govenor feared the Jewish leaders going to Rome and getting him fired like they did to a predecessor.
Hence the Pilate washing his hands, symbolizing that he did womthing that he felt he had no choice but to do. Had Jesus been a rebel there would have been little basis for the hesitation or felt need for disavowing guilt in executing an innocent man.
It amuses me how so many modern minded people simply start from the proposition that there is no written history for the early church when Christianity probably had better documentation to its origin in the NT books/letters and the writings of the Early Church Fathers than any other establishment of any other institution prior to the printing press.
Show me a flaw in the Gospel of Mark that you wouldnt find similarly in Ceasar's conquest of Gaul, and yet modernists ignore the gospel and accept the CoG right out of the gate. This is just another manifestation of modern hubris and bias against religious thought and expression.
