Gah, I try not to get dragged into this stuff but here goes anyway.
Short answer that makes me sound like a dick: yes.
Long answer that hopefully sheds some light on my perspective:
Christians view heaven/hell like a natural law. When asked if I think nonbelievers are going to hell, it's like asking me if I think someone who jumps off a building is going to hit the ground. The answer is yes whether I want it to be or not. From my viewpoint I'm not judgmental in my answer, I'm just stating a fact.
I have to then often face the follow up question, "so you believe that good people who aren't Christian go to hell?" My answer has to be yes, because I don't believe heaven and hell have anything to do with behavior at all. I don't see the question as bad-to-good on a sliding scale, but perfect-imperfect as an either/or. And we are ALL imperfect. That means no number of good or bad works affects our final destination.
I see Christianity as one of the LEAST judgmental religions (am expecting that to be quoted out of context repeatedly and with slurs) because I don't think God uses our behavior to judge us in the least. Law of nature - we're all hellbound to begin with. God extends his offer of mercy to everyone equally. God also respects our choices; if we choose not to take him up on it he honors that decision.
Does that mean there aren't asshole Christians that take delight in the idea of condemnation, judgment and damnation? No, there are plenty of those. Does it mean that there aren't Christians out there that try to get involved in judging others right now on earth? No, clearly there are plenty of those too. It's unfortunate and I'd rather argue theology with them than non-believers any day. I can't judge any non-believers; God gave everyone free will and it isn't my place to try to take that away from anyone. People who call themselves believers though, THEY place themselves under accountability from other believers, and I have an obligation to try to correct them when I see them off base.
Flame on, OT, flame on. After 9 years here I guess I can take it.
[edit] Just have to add, I have absolutely nothing against anyone of any religion or lack thereof. I absolutely 100% respect everyone's right to believe what they believe. I don't want to see ANYONE go to hell, and so believing what I believe makes me sad quite often. But again, going back to the natural law comparison, I can't simply decide I don't like the idea of people hitting the ground when they jump off buildings and thereby prevent it from happening; the best thing I can do to prevent it from happening is make sure that the jumper has at least heard my understanding of gravity before they make their decision.
