Nonsense.
The more assertive atheists also don't seem to like the idea of him being a real man either, as that might undermine their idea that there is no value in religion.
Bollocks.
I'm with Bill Maher on this one, who said something to the effect "If Jesus Christ floated down from heaven onto the fifty yard line at the super bowl, I'd go 'huh....look at that....I was wrong'. But he isn't and he won't so it doesn't matter".
It isn't that some Atheists "don't seem to like the idea" in the least. It is more that, and I am speaking only for myself, I recognize a parable, a play, a fable, a myth and a made up story when I see them.
The story of Jesus who is the Christ is CLEARLY a fable. It is a play. His story is a fable that relates the movement of the sun and the moon through the skies. THAT'S IT! The only reason it is even remotely suggested that he was a real person is because it is needed to perpetuate the entire myth based religion that is Christianity. The idea that mankind is inherently flawed and needs redemption. As soon as more people start realizing they aren't flawed, just human, the sooner we can shed these absurd, intellectually primitive belief systems.
"Religion is regarded by the common people as true, by the wise as false and by the rulers as useful."
