While some believe the Bible is true in every detail, the majority of Christians know it to be allegory. Lumping all Christians together is rather foolish, disengenuous and, stupid for a comedian who does an elitist prick shtick.
There are some stories in there that, if they are allegories, they're not allegories for anything sensible or good. What is God murdering all of humanity an allegory for? Is it a warning to not be wicked, or else God will kill you? I guess the rest of the people who had nothing to do with you are collateral damage. It's a warning that God's aim ain't all that good when it comes to purging the world of evil then. It's senseless ultimately. It doesn't work as a true story or an allegory.
Bet you don't think the birth and death of Jesus are allegorical though. That's too central to Christianity to give up, even though the bible declares all those other stories with the same straight faced authority as it does the story of Jesus. There's not a wink or a smiley in the whole book to let you know that it's
this is the one we're telling with tongue-firmly-in-cheek, and
that is the one that really happened. No, you have to separate them yourself, based presumably on what makes you feel the best about life. That may be a good way to put your mind at ease, but it's a very bad way to get at any kind of truth. Some of us would like to know what the truth is, regardless of how that makes us feel. We see those stories you claim to be allegorical and count them against the veracity of the whole.
