Morality changed. Saying the bible was morally wrong is only saying that you want to apply today's morality to people that lived in a different age.
In any event, if you accept that morality can change and the Bible can be incorrect as a source of modern moral values, then it's hard to see what good it is as a guide. If we disagree with it, we have to substitute our own judgment, since "morality changed". So if you accept this view, then that condemns the Bible to be useless a source of moral guidance.
Again what you are doing is saying that today's morality is absolutely correct and that all preceding version and all the future versions are wrong. But at least we agree on the Bible
It could be that in 1000 years time, factory farming, or mass abortion, or something else we take for granted is seen as a heinous offence.
I'm not arguing that we should not enforce our moral standards - OP asked for proof objective rights exist. I genuinely don't think they do - our morals and our rights are part of our culture.
Where did anyone say that? How did you draw this conclusion?
This is a strawman argument. It even adopts your moral relativist/populist notion of "today's" morality!
Statement 1 by JoelKatz : Slavery was *always* a moral abomination, whether people realized it or not.
Statement 2 by me: What you are doing is saying that today's morality is absolutely correct and that all preceding version and all the future versions are wrong
That's where. Until 500 years ago, slavery was not a moral abomination. Morality changed and now it is. JoelKatz statement that it was always a moral abomination is applying today's morality to an age where it doesn't apply.
All you're doing now is repeating yourself, while offering no explanation as to how you bridge this epic gap whatsoever. WTF is "today's morality" if not an extension of YOUR relativist argument, not Joel's?
To break down just a couple of these holes:
* Where do these claims about "future versions" come from?
* How could just being right about slavery make "today's morality" absolutely correct?
This is just like that "immovable object" argument a couple pages back. You're defining everything in your own terms but because your terms are nonsensical, the concept you translate sounds nonsensical.
To adhere solely to "today's morality" is simply amoral - even if you don't believe in a God, there are at least some absolutes within humanity that haven't changed during our history or across cultures.
