I'm just a kid, I don't have many opinions on things like this that have solid foundations. I can get behind a bit of universalism. For example, I don't believe Ghandi will go to hell for not being a Christian, or that Mother Therese will go to hell for not being Orthodox. I think that all have a chance of being saved, but it's somehow more direct for Christians.
That's my thought. I don't agree with total universalism at all. I believe very much in the OT concept of Olem Haba (picked that one up at the synagogue,) where we will all go and be with God when we die. Those who loved and served Him will experience pure bliss, and those that hated him will experience pain. I find this much easier to understand, so it's what I think of when I think of the "hereafter."
The way I see it, Jesus Christ is the way, the truth, and the light (as he told us,) and no one comes to the Father except through Him. Surely, though, if a non-Christian lived a life of charity, tolerance, and love, God will look upon that person with love and compassion (after all, His mercy endures forever.)
But I'm no theologian...
