Attempting to disentangle modern faiths from their culture and social controls is a fundamentally flawed idea and gives no one pause. Everyone is primed by even decades of training to dismiss one aspect of holy text for another. And even if you could win that argument, a "personal" relationship with their deity (actually: their status within their religious community) will still reinforce their position until their rationalizations can be drafted.

Trust me on this. I spent years learning how to call Catholics hypocrites while dismissing every book in the new testament. We were very good at it, and they were very good at pressing us.
