What are 'biblical values?' Are they the Law of Moses, or the Noahic Covenant, or maybe the Edenic covenant? To be honest, 'biblical values' seem to be based on cherry-picked verses that support specific agendas. Think of the sins you believe to be so ardently wrong and must be legislatively punished.
Then ask yourself, what does the Bible really say about those sins? Are those the sins God judged Israel for? Did the major or minor prophets spent time warning of culture wars, or did they condemn a nation that turned its back on the stranger, the poor, and the disenfranchised?
You could also ask if your version of 'biblical values' is truly pro-life. Have the recent changes in reproductive rights (in the name of 'biblical values') increased maternal mortality rates and is it continuing to endanger women?
Instead of cherry-picking a set of verses that support our cultural bias and labeling them 'biblical values,' maybe we should just ask ourselves 'what would Jesus do.' Maybe we should consider Matthew 25, when Jesus sends those who did not care for the 'least of these' away, while embracing those who visited the needs of the poor as if they had visited Him and provided for His earthly needs.
