I am an agnostic, i think there is probably some kind of being that created everything, but i'm not gonna pretend i know his/her name, or how they created the universe.
For me, it kind of pisses me off when i'll ask a co-worker of mine (he's jehova witness) and i said to him, "so, based on the teachings of the bible, only christians will go to heaven, that true?" He replied, "sure, that's what it says." So then i said "well what about people who are pretty much saintly, but aren't christian. You know, like Ghandi, or Mother Teressa, just because they don't practice the same branch of Christianity as you do, you can't really deny that they were good people who tried to help out everyone they could. But....they're still going to hell?" He said, "yup."
I pretty much see it like this...if you try to be a good person, help out people, and have a good fulfilling life, then you shouldn't worry about eternal damnation in a lake of hellfire. If there is a God, i doubt he would cast a Buddhist monk into a lake of fire for all eternity just because he wasn't a christian. And if God doesn't exist, then you've got nothing to worry about.
Also, the whole "convert and you're fixed" thing kinda bugs me too. You could be a former serial killer/child rapist, convert to christianity, ask for forgiveness, say you're sorry, and shah-bam! you're now as clean as the guy next to you, all because you said "sorry." That doesn't fly with me.
