WLC free will and omniscience

[MindForgedManacle]

1 is an unknown, as Chad has illustrated. I err on the side of future knowledge.

Has he? I'm fairly certain Chad has vehemently denied that God knows the future, since on his view the future does not exist. You however have just accepted that God does, on your view, know the future.

2 is true only in Gods realm, and not for time bound beings. It would be a fallacy to conflate the two. Determinism is some mixed up hooie.

You are worse than a post-modernist dude. You're saying that God knows the future of OUR temporal realm, so clearly this extends beyond his "timeless" realm. Further, for God to know OUR realm's future, the future has to exist. But if God knows the future because it's an already existing state of affairs, that entails determinism by definition.
And no, it isn't a fallacy at all, because I haven't equivocated on anything. You however are making a special pleading fallacy.

3 is therefore nonsense

And yet it is not, given the above.

4 I believe this. I don't 'know'

I didn't say you "know" it, I said it's something you accept, i.e believe to be true.

5 libertarian free will exists in its own domain which is independent of a timeless perspective. It is correctly called free agency.

Libertarian free will cannot exist if the future is known, which is what you've said repeatedly. You're saying that God has knowledge of THIS temporal realm's future states of affairs. That entails determinism and contradicts libertarian free will because then there is no "ability to do otherwise", which is the definition of libertarian free will.
