I understand and pretty much agree with you; but we live in a country where laws and regulations are not really guided by any specific religious belief or specific moral system. They’re the product of a consensus morality and science.
Maybe someday we’ll get where you want us to be. (I’m personally hoping that science someday moves toward encompassing metaphysical issues. I don’t expect to see it in my lifetime.)
That is true, but we can and have joined with like-minded people on particular moral issues to break through the common consensus when it is immoral and make a change. We have seen this happen in a number of areas in our history including slavery and most recently abortion. They kept telling us that it was the settled law of the land and that the majority of Americans supported abortion but since Roe was overturned, we've found out that is not really the case. You can also say much the same about human child sex trafficking. Everyone knows it was happening, but it has take a series of recent events and the activism of a few to bring it more to the fore than it has been.
