That's why we have laws against murder, thievery, rape, etc. People's religious convictions drove them to vote for such laws.
I doubt it. The concern that informs such laws is an inherent sense of justice and ethics. Occasionally these sensibilities find their way into religious codes, but that is not their origin. Nor does the presence of certain mandates in a religious code make themethical or just; note that the U.S. outgrew not suffering witches to live, for the most part, and no longer puts people to death for sodomy or adultery, in spite of the clear mandates on these points in the Old Testament of the King James edition. Individual sensibility is the origin point.
