Most religious people aren't actually using the Bible as their main book so that wasn't the fix you thought it was.
Christianity is around 30% in the world. There certainly are plenty of people in other religions who pick and choose what they want in those religions. Now if you want to apply it to the US it becomes more of a fixed situation because Christianity or people claiming some 'flavor' of Christianity probably is around 2/3 or more of US religions.
But growing up in a very Catholic household, having been around many other Catholics in an extended family, going to Catholic school. Going to a Christian college, being around other people of the Christian faith. Having dated a very religious protestant woman and even had an ongoing business relationship with a pastor (well former now) of a large church in Philadelphia)
The amount of 'picking and choosing' is so laughable.
