I'm not sure it's possible to unpack your conclusions, but I'll give it a shot.
What I believe about the final state of the unrepentant has nothing to do with the fact that I can't know with certainty who they are in this life.
Not sure what my "preferred hang-out" list has to do with this but 1) my children are not Christians, and 2) my chief concern for the type of friends they have is that they're well-behaved.
I've already stated here http://www.dailypaul.com/266275/judge-napolitano-why-you-can... that salvation is defined within each religion.
What does asking a Catholic Priest for salvation have to do with anything? Salvation to eternal life is God's choice, not ours:
"For he says to Moses, 'I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.' So then it depends not on human will or exertion, but on God, who has mercy. For the Scripture says to Pharaoh, 'For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.' So then he has mercy on whomever he wills, and he hardens whomever he wills." Romans 9:15-18
