I was thinking about this earlier, what if Jesus had been executed as a false preacher, prophet or something unashamedly inciteful like proclaiming to be 'king' of the Jews due to unfiltered, admittedly fevered and almost ferocious preaching from his late 20's onwards?
I can't imagine he'd last past 35 or so within the Roman occupied states.
EDIT - Removed the references to Jesus as a 2000 year old man.
