There is an Elohist list at Exodus 20 and a Yahwist one at Exodus 34 that contains such gems as "You shall not cook a kid in its mother’s milk." Any intelligent adult could create a more useful list of ethical precepts before the end of a coffee break.
Yes, if not cooking a kid in its mother's milk was the pinnacle of the Mosaic Law. But it's not. In fact, it's a very moralistic code that's rich in ethics, compassion and morality. Militant atheists revel in the same things that Satan does, and that's accusation. They stand collectively as an adversary and accuser of God. The mother's milk is life to her young. That the Lord would see the horrific ramifications of this and forbid it recognizes the sacrifice of life in both the mother and the kid.
The law also forbade the netting of all of one's fig trees to protect them from hungry birds. You could net some, but you had to leave a portion of them unnetted so as to feed the birds. There were similar provisions for animals and the ethical, compassionate use and treatment of beasts. Crops could not be fenced, but had to be open to allow the hungry to eat. The people also were taught not to gather a farmer's food for their own profit, and there were ethical treatments and protections for both beasts of burden and bonded servants. I lack the time and space to tutor you on these things, but the laws of God to the ancients have never been equaled or excelled by mortal law. But to accuse, you, like the great accuser of God, must stoop to dishonest levels to oppose Him. Why not list what you feel are the immoral codes of God's law? Where was He petty, vindictive, unfair?
It is interesting to compare The Satanic Temple's Seven Tenets. I think you might agree that it makes Yahweh's rules look like they were written by a Bronze Age power-hungry, misogynistic priest.
Yes, and where do you find Satan advocating those seven tenents? What about those he endorsed anciently, such as to murder to get power and gain, torture animals, human sacrifice, including the throwing of living infants into the fires, and the decadent immoral practices of sacral prostitution, bestiality and other immoral practices forbidden by God. There were plenty of misogynistic priests anciently, but they were primarily the priests in the employ of the Adversary, not God. You also are wholly ignorant of the levels of wickedness in pagan society or, as we've seen, in God's law, yet you pretend to sit in judgment of His ethics. Yet where would any of us ever have conceived of ethics, or evils, were it not for God, who is the author of those ethics? Off not for Him, they would not exist.
