Actually im not inscrutable on this point at all.
While this fellow champions the relevancy of Free Will… he is poised to make the Genesis 1 pre-Adamites as creatures WITHOUT free will…
… because he doesnt think God’s Image has anything to do with Moral Agency (the universal implications of human free will).
In the meantime… he stirs the manure on many threads by bringing up Free Will like its the only point that matters.
I think @swamidass has already noticed this angle…
