Do I believe Atheists are going to hell?

To clarify here, Catholicism certainly does not teach that people of other faiths are damned, and that only people who died Christian go to Purgatory. We make no such judgements on the state of souls that way.

I'd like to further add to this in case I haven't been clear enough on my earlier posts. I do believe that Christ is the way to salvation. But as Catholics we do leave an open door at least to the possibility of a person following Christ without the explicit knowledge of doing so. Some of us are more optimistic/charitable than others about this. I'm in the former category.

Where might I find an intelligent discussion on this with reference to Catholic doctrine on said issue?
