I somewhat disagree. As climbers, we are part of a small community. When someone in that community dies or gets hurt, it strikes closer to home than when the same happens to someone that we truly have no connection to. I have some friends who are into skiing truly nasty terrain. Hence, when I read about the skier/boarder fatalities on St. Elias, it hit home, as one of the unfortunates could have been one of my friends. Same with climbers. The guys who died on Snow Creek Wall are a prime example. I had no idea who these guys were. But one of my friends knew one of them. Could have been me, or someone I know. Due to this effect, I think most people do not offer condolences as a mindless courtesy. They mean it.
As for the flame wars, I have noticed the flaming occurs usually when someone gets into trouble up there, but makes it out fine. Look at the Lambone/Glacier Peak thread. People are worried when their friends are in trouble, even if they know that person only through internet contact or common friends.
As for risk, I think about the risks I take often. I don't know why I climb, as it is an unnecessary risk we choose to take. That's probably part of the attraction, but I'm not sure.
Here's to life.
