On one end, we have people making jokes about "steve jobs dies, a million weep, a million die [of hunger], nobody weeps". And "why is everyone so busy about celebrities dying of overdose? Look at this awesome story of how a man died to protect his squad/team/family/group!" These would be valid claims if they hadn't been so comparing - "millions are dying of hunger" and "remember what that hero did" is perfectly acceptable. Ridiculing someone else's death with a comparison is not.
At the other, we have excessive things like what I just saw straight on CNN. And I quote:
"15 die in Baghdad bombing"
"Mexican deadly prison melee"
"Teen mom and child found shot"
"3 dead in washington avalanche"
And suddenly the announcer says...
"It's tragic when the worst thing you thought could possibly happen occurs. And today, it has. Whitney Houston has passed away." (I think this was a clip for a previous airing.)
People are personal family members and heroes to at least one other. Treat the dead with respect, respect those they left behind, and move on. Stop comparing one death with another. Each is tragic in their own way.
... And next step up are the people saying "BUT 200,000 PEOPLE DIED FROM NUKES!"
