I am a bit late on this one. I think ignoramus asked a good question worthy of looking at, even if I am not qualified to answer him properly. Of course there is valuable cultural history knowledge buried in there. Just dismissing the whole book as a pile of poo is throwing the baby out with the bathwater. Leaving the God fairy tale aside (the bathwater) the problem is that not much is verified by other sources. Jesus and his brother James are mentioned in some Roman writings I think.
It's not immoral to eat meat, abort a fetus or love someone of the same sex...I think that about covers it
