Bible believers, as once I was, tend to not want to discard the Bible completely, hence they fall back on the "some of it is good" argument. A Poster on here once described that approach as " picking pennies out of dog s**t".
I now see the Bible for what it is, a collection of writings with no Provenance, that comprise the Theology of the times of the writer, that all the writers had an Agenda, which often involved them writing under a Pen-name, and that any "wisdom" contained therein is of its day, and has either been made entirely redundant or improved upon.
Is it as "fake as the JW's " ?
In as much as it claims to be the word of god, and JW's claim to be the true religion, yes.
Both claims are False.
