and have we created a better society by sanctioning the freedom of the individual to choose pornography, adultery, abortion, divorce, homosexuality?
Abortion is working a harm against someone who should have a vested protection under the law. It's wrong to conflate that with a number of other things that are properly a matter of choice for the individual.
We don't sanction adultery, which is one grounds for breaking the marital contract and actionable as a tort in most jurisdictions else (tortious interference with the marital estate).
Every religion I'm aware of sanctions divorce, though the root is more or less restricted from faith to faith and the same is true at law in relation to jurisdictions.
So is there a decent question among the mistakes you make here...well, not mistakes so much as an intentional attempt to lump things together that don't belong together?
Sure. Here it is: are we better for permitting people to make moral choices that don't interfere with the exercise of another's right?
Yes. God gave us that capacity to begin with, which was the point of my answer in the other thread.
