Aside from losing a family member recently, the reaction of the world in general to the Newtown shooting has got me down. The victims' bodies hadn't even gone cold yet before I had to hear from far too many people- both those I agree with and those I don't- finding ways to use 20 dead children to bolster their political platforms or justify their life's choices. The fallout from Columbine was fucking awful, and now we get to relive those times all over again, only this time the bodies at the center of it are even younger.
Also, Revuhlooshun's got it right. It's astonishingly difficult to get anyone to accept a truth that doesn't benefit them unless they felt they came up with it themselves. I've both dealt with this behavior and experienced it myself- and I'm not completely convinced I'm not unawarely doing some awful thing or another.
