Then you're down to opinion vs opinion. Add into that the work that Bart Erhman has done on the veracity of the texts themselves, as well as the fact that the bible was assembled by committee (of men).

We're all entitled to our own beliefs, so I normally wouldn't care, except there are active factions trying to make the US be ruled by biblical law. So in that context, this act of interpretation is very much of everybody's interest.
