I didn't say ignore it. I said acknowledge it, evaluate if there is anything you can contribute to helping the situation, and then move on.
So what did you gain by reading hours upon hours about the destruction of Hurricane Sandy? Don't get me wrong, I was on Jazzfanz posting about the night it hit New York City with my TV blaring in the background out of curiosity. Guilty as charged. But there's no ultimate benefit from it, and It certainly dragged on me a bit as I thought of a few heads I know back there, wondering what they were doing. I did what I could, I gave a little money, but let's say I spent 6 hours total immersed in that negative news event? What did I get? A few factoids to ramble off in a few years while looking back at it? Humans can only take so much before it starts seeping into their lives.
I never read hours and hours about the disasters or horrendous crimes like this new school shooting. My main point was that to me it seems that your stance places us on a slippery slope and I am not sure I want to be on that slope or not.
