Got an issue here's a tissue? Stunning.
Look kiddo, you'll find that not everyone needs to rehash what a tragedy is in order to recognize it, and most well-adjusted folks aren't going to dwell upon it, either. It's abundantly clear to everyone that these young people were cut down far before their time, and that this is a tragic thing, almost as tragic as your continued insistance on breathing my air. You don't represent them, you don't represent some righteous beacon in the absence of civility, you don't represent Shit beyond pretentious teen faux-enlightment and delusion.
Perhaps when you're a bit older, your soul calloused from soaking in the unfair reality that is life's total lack of fair-play, and have fully grasped that your prayers and mourning amount to fUck all, you'll get it, but with any luck you'll realize your destiny as a soft place for a bullet to land long before that can happen.
Now go cut yourself some more, you little snowflake.
