My moral standard is the Bible. Whoever God says deserves the death penalty deserves the death penalty. There is absolutely nothing wrong with believing that, and just because you happen to have a very strong opinion to the contrary doesn't make your opinion right.
You have not revealed your moral standard, yet. You said something about empathy, but that's not a valid standard, since those kinds of feelings can be wrong.
In this discussion, one of us is being open and clear about what the correct moral standard is. The other isn't. That's you.
If you don't like the Bible, just say that. Don't pretend to take the high ground and call other people moral monsters based on your emotions. Those aren't a moral standard.
God is right. You aren't. I'm sorry you don't like that. He's been around longer than you, and he created the universe. He knows what morality is. You don't. What he says is always right. He's infallible. You aren't.
Now by all means, if you don't have a rational argument, please keep repeating your accusation (so far, completely arbitrary and unfounded, based only on your personal opinions and feelings) that the Bible is wrong, and that I am a moral monster.
It may make you feel better to do so, and will have the added benefit of demonstrating clearly to me and to everyone reading this that you have nothing else to fall back upon. It will demonstrate that your assertions are arbitrary, not based on rational arguments or an objective standard, and can therefore be dismissed as merely your personal feelings on the subject, and nothing more.
