I can't say as I agree with the general tone and statements of that article.
Obviously, every child killed is tragic but to act as if its near epidemic proportions and you're practically sending your kids to wanton slaughter by sending them to school every day, that's a bit overboard.
"Hundred of times more likely", nope. Sorry. If fires kill zero and one child is shot, that's INFINITELY higher (1/0), actually it's undefined.
We shouldn't use tragedies to make political points any more than the other side should and when we make points they should be accurate and honest, not sensationalized for effect.
There are some good points and certainly situations and ideas to consider in that article but I tend to ignore anyone from either side if they start making up numbers and sensationalizing for dramatic effect.
