Burying your head in the sand is why events like Sandy Hook, VT, and Columbine happen.... Please don't bury your heads in the sand and ignore the negative aspects of humanity. It does no good. I have three kids that I look to for my happiness, so spending time debating and thinking about terrible, disgusting events like what happened Friday is possible. If I start feeling too down, I just go spend time with my kids.
I also agree entirely with Ton. The media looks for negative stories above all else, because "car wrecks" are what sells.
