Humor is great, but do you feel it should be used on articles and threads regarding bombs, damage, destruction, murder,and death? It seems recently that almost every thread of a somber, serious nature is hit with little quips, most of which are not even funny or clever, and seem out of place.
I think threads like:
Lice offer clues to origin of clothing
would probably be a better target for cute quips and jokes...
I don't know. Some of the comments on the deaths of terrorists are pretty funny.
But your point is well taken, sometimes it is inappropriate, but it also is a natural response for some to add humor to uncomfortable situations. I don't think it's necessarily disrespectful.
