The Abrahamic sacrifice of his son.

[Brian37]

You brought up Abraham and Noah, I know the stories. All I told you is that you cannot defend the morality of either. Not because I hate you personally, I don't.  Those stories are mythology and were written by the people of antiquity for the people of antiquity.

Yet in my perspective, neither was Abraham commanded to literally kill his son, neither was the family of Noah the only survivors (he had people following him that were referred to as low lives by their people).

I don't care, even as a "metaphor" it is still immoral. Not even if you put that in a "Cat In The Hat" book for children.

If you had two children, say 5 or 6, and you went up to one and said, "Hey prove your loyalty to me, here is a knife, kill your brother" only to say, "Just kidding".

If I saw a parent doing that to their kids, again, I would call the police. It is horrible even as a metaphor. 

The REAL reason stories of "sacrifice" exist in the ancient world, even in polytheism, in all of antiquity, was because BACK THEN humans lived under local tribal city king states ruled by that local royal family. Back then the mortality right was much higher, and if you were a surf, your survival depended on your loyalty to that local ruler, so if that ruler asked you to do something you did or risk arrest or death. BUT THAT WAS COMMON in all of antiquity. THAT is why that story exists, not because it ever happened in reality.

TODAY, technology and education have moved us away from such antiquated barbarity, and no sane psychologist would call the request of killing your own kid moral.

AND AGAIN, I would say the same to a Christian and Jew if they brought up the same story. It was written for the people of that time, and nobody back then had any modern understanding of human biology or how to raise a kid to be mentally healthy. It was a very authoritarian world EVERYWHERE in every religion. BACK THEN.

And again, if I overheard my neighbor calling for someone to murder their kid, or even their pet cat or dog for that matter, I would call the police. I would think they have something mentally wrong with them.
