I see your problem with the reasoning "any current Christian "knows" Jesus in a way that is clearly and conclusively different from how former Christians "knew" Jesus.. so anyone who claims they knew Jesus but no longer believe was never a true Christian in the first place (according to them)."
In the belief that once saved, always saved (which I believe). I don't think Christians should make that call. A lot of them don't like the idea/thought that you could know Jesus and then years later be an atheist and still get into heaven. I believe it's the same type of feeling that make people uncomfortable saying Hitler could get into Heaven. If you have any unanswered questions about the once saved,always saved belief, I'd be happy to share my perspective while we await answers to your other questions.

"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
