Thanks for the link. Here is a summary from your link. Molinism is similar to Arminianism which is in opposition to Calvinism.
“Biblically speaking, Molinists are more in line with the Arminian view. God chooses who will be saved because He knows who would choose Him. However, Molinists are more philosophically sophisticated than the typical Arminian. For example, William Lane Craig avoids the criticism that God’s decisions are dependent on man’s decisions by holding that God’s middle knowledge is not derived from His knowledge of the world. Rather, God’s middle knowledge is based on His existing natural knowledge. In this way he hopes to uphold God’s perfect omniscience. So, today’s evangelical Molinists are basically philosophically sophisticated Arminians.”[4]
I think a better response to “Is it Fair” is according to the Apostle Paul:
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, [2] but on God, who has mercy. 17 For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.” 18 So then he has mercy on whomever he wills, and he hardens whomever he wills.
19 You will say to me then, “Why does he still find fault? For who can resist his will?” 20 But who are you, O man, to answer back to God? Will what is molded say to its molder, “Why have you made me like this?” 21 Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? 22 What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, 23 in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory— 24 even us whom he has called, not from the Jews only but also from the Gentiles? - Rom 9
