I think it's important that in times such as this, we all share a deep sense of loss and pain. There are always some tacky Bubbas who'd rather stand in the back of a funeral and trade farts; maybe even break into a fist fight.
There are times when we need to honor our mutual loss and national grief. This is one of those times. We need to be in prayer and to respect the gravity of this historical moment, IMO. Our president has set the mood and I will honor him and our lost astronauts by not commenting further.
