I hesitate to expound upon what is really a hijack of the OP - I had intended merely to point out that not all atheists accept the omniscience paradox - but since Diogenes has participated in the hijack, I take it he doesn’t mind.
Czarcasm: You’ve introduced an ethical argument of what God ought to do with his omniscience. This doesn’t logically relate to whether the omniscience exists in the first place. As for the ethical argument, theists have several replies, of which the most popular in my observation is that good ceases to be good without the ability to choose evil.
Diogenes: Most of this is subject to the same objection just stated. Further, you’re simply playing with the oddity of time paradoxes. That God knew what would happen doesn’t make it happen. Moreover, you’re assuming God creates each and every one of us. I realize some fundies believe this, but it’s not a necessary condition to Godness, and has nothing to do with omniscience.
Contrapuntal: Actually, that’s precisely my point. Omniscience is just information. It doesn’t cause anything.
Voyager: Not illogical if the lines converge.
Chief Pedant: Same response as to Czarcasm and Diogenes. What ya’ll are really complaining about is what God does with his omniscience.
monavis: Again, same response. Only here, you’re doing what I call the angry atheist thing. If God exists, why doesn’t he stop the madness? That has nothing to do with the omniscience paradox. And if God doesn’t exist, there’s no point in being angry with him.
Aside to All: I went ahead and defended the more inclusive definition of omniscience because that’s the more familiar one. Were I a theist, I would plunk for a different definition, viz, that God knows everything happening now and that has ever happened, but is subject to the arrow of time. I honestly don’t see how this would undermine his Godness (I’ve seen Liberal make a form of the argument). And, of course, it eliminates the paradox completely.
