When someone starts a discussion (on the CR, a “thread”) about a tragic fire and how we should relate to it in terms of ruchniyus, and someone’s first or only reaction is about smoke detectors and hot plates, that person (in this case a couple of posters) can’t help but come across as minimizing the mussar aspect of it.
I also don’t think one needs to know “the” point to see that someone else has missed it. We all need to look at our own shortcomings (not everyone else’s) and try to improve. If someone fails to to do this, he or she has indeed missed the point.
And yes, we should all have working smoke detectors and exercise extreme caution with fire.
