As if that in any way addresses his argument...
Made up to suit a narrative, just like saying "official".
No, it's not "made up."
Saying it doesn't make it so.
Or it sounds like scripture.
Scripture is not irrational.
Calvinism is, and makes God unjust.
Depends on how precise you want to be with the word.
No, God is not arbitrary. Redefining words is what Calvinists do to make their position seem scriptural to others, because then they can rip things out of context that come from scripture and make them say whatever it is that fits their doctrine.
Romans 9
(13) As it is written, “Jacob I loved, but Esau I hated.”
(14) What shall we say then? Is there injustice on God's part? By no means!
(15) For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”
(16) So then it depends not on human will or exertion, but on God, who has mercy.
Love and hate is a Hebrew idiom that means "to love and love less."
Jesus said that if anyone comes to Him and does not hate his father and mother, wife and children, brothers and sisters, and even his own life also, he cannot be His disciple.
He's not saying that you literally have to hate them, for that would contradict His command to "honor your father and mother!"
He's saying that you should love Him so much that it's as if you hated your father and mother, et al, in comparison.
The same idiom is used by Paul in Romans 9, and on top of that, Paul is not talking about the individuals Jacob and Esau, but rather, he's talking about the nations that came from their loins.
Paul is referencing Genesis 25:
Isaac was forty years old when he took Rebekah as wife, the daughter of Bethuel the Syrian of Padan Aram, the sister of Laban the Syrian.Now Isaac pleaded with the Lord for his wife, because she was barren; and the Lord granted his plea, and Rebekah his wife conceived.But the children struggled together within her; and she said, “If all is well, why am I like this?” So she went to inquire of the Lord.And the Lord said to her:
“Two nations are in your womb,
Two peoples shall be separated from your body;
One people shall be stronger than the other,
And the older shall serve the younger.”
So when her days were fulfilled for her to give birth, indeed there were twins in her womb.And the first came out red. He was like a hairy garment all over; so they called his name Esau.Afterward his brother came out, and his hand took hold of Esau’s heel; so his name was called Jacob. Isaac was sixty years old when she bore them.So the boys grew. And Esau was a skillful hunter, a man of the field; but Jacob was a mild man, dwelling in tents.And Isaac loved Esau because he ate of his game, but Rebekah loved Jacob. - Genesis 25:20-28

Guess what ended up happening with those nations?
The Edomites (Esau took the name Edom, thus the nation that came from him are the Edomites) were conquered by David and he forced them into labor as his servants.
Do you really think that God did not love Esau (and by extension, the nation that came from him)? Do you really think that God is arbitrary in whom He loves?
If God is arbitrary, then He is unjust.
