I would disagree with the proposition that people are in any way actually OK with death. I don't think the problem is that people are at peace with death too much; instead, it's an issue that people are so afraid of death that they don't talk or even think realistically about it at all.

It would be pleasant to me if this were true, but the talk I hear from some sources is actively pro-death. (Specifically, the "But fading into darkness will be so nice" and "I look forward to the Next Thing" camps of thought.) That is to say, when I bring up cryonics, the thought is actively abhorrent to these people. They profess quite strongly to prefer dying to cryonic preservation because having a frozen, inactive brain will stop their Soul from Departing. So... I can't tell if this is just really, really powerful belief in self-deception. The sentiment feels believed to me, which is what's so concerning.

I agree strongly with your last point, and am having trouble with how to express that agreement, so we'll leave it there. (Augh, words!)
