Please reread my post above. I stated 'hell' is a result of the choice of man to separate himself from God, not a threat by God. It is not an Argementum ad Baculum. You should work more on reading comprehension and less on using inappropriate Latin phrases.
Your perspective and interpretation are way off. Not surprising, given your lack of reading comprehension (see above).
So, by "separation from God" you mean that the rest of us will get to go to the Elysian Fields or Valhalla or the Duat or whatever, and only you Christians will end up chanting "Holy, holy, holy, Lord God Almighty, who was and is and is to come" forever and ever? In that case, only Christians go to Hell.
Every other time I've seen a Christian use the "Hell = separation from God" argument, they go on to explain that since no good or pleasant thing can exist apart from Yahweh, Hell is still the epitome of misery and suffering (all the fire and brimstone descriptions are metaphors for this), even if there aren't demons poking people with pitchforks. If this is your interpretation, then you're still using an Argumentum ad Baculum ("Believe what I say or you'll really, really, really suffer! Forever!"), with a little semantic lipstick on the pig.
On the other hand, if the "sophisticated" Christian theologians are correct in arguing that Yahweh is the metaphysically necessary Ground of Being/root and source of Existence as such, then "separation from God" would entail non-existence. IOW, "in Him we live and move and have our being" could not apply to anyone separated from Him (since such separation is incompatible with being "in Him"). Therefore we nonbelievers would Just Die (cease to exist as "us" in any sense) exactly as we expect. On the other, other hand, it doesn't make a lot of sense to say that a non-existent person is "separate" from Yahweh or anything else.
On the other, other, other hand, a Christian might assert that Yahweh would continue to prop up the existence of unbelievers so that they could eternally experience the misery of being alone in the Void (or whatever a separate-from-Yahweh existence is supposed to be like). For Yahweh to remain "immanent" within and continually exert will/effort to sustain those he wishes to make miserable suggests an especially intimate kind of sadism on his part. And maybe masochism too, if "omniscience" incorporates the "knowledge" of direct experience rather than being limited to an academic awareness-of-facts: he would have to experientially know ("in the Biblical sense") exactly what each and every person in Hell is feeling/thinking/experiencing at every instant of their tormented eternity.
H, the whole "separation from God" argument is predicated on the idea that Yahweh's perfection cannot countenance even the tiniest most infinitesimal amount of "sin," so that any "sin" not covered by the Blood O' Jesus must be wholly extirpated from before the presence of the Lord. If so, then Yahweh could not perpetuate the existence of unbelievers since he would also be perpetuating their "sin" and being immanent with it.
Or is "sin" a self-existent force on a par with Yahweh? Since it affects Yahweh so strongly that despite his putative omnipotence and inherent indestructible immortality he cannot endure its presence, it cannot be substantially weaker than he is and it cannot depend on him for its existence (otherwise Yahweh would be the author and creator of "sin"). So maybe Yahweh can somehow transfer the burden of sustaining the existence of unbelievers to "sin" somehow. Hmmm...if it is impossible to have "sin" without a capacity for "sin" (i.e., no lust without attractive members of the appropriate gender, no gluttony without food, no pride without something to be proud of, etc.), maybe that means that Hell will be the ultimate party! If so, that beats the pants of of the Eternal Church Service (see the descriptions in the Book of Revelation) Christians are promised! Plus, we get Carl Sagan and Mark Twain and Hypatia of Alexandria, while they get St. Augustine and Carrie Nation and Jerry Falwell. Unbelievers, FTW!
Of course, all that stuff is your swamp to drain, not ours, as we have no obligation to create a logically consistent Christian theology to debunk.
