Our generation has never known a world without the threat of school shootings. We were practicing active shooter situations before we knew how to do long division — our teachers may have used phrases like “Code Red” or “shelter-in-place,” but we know what they really meant. In middle school, we joked about trench coats and heavy metal and “Bodies” by Drowning Pool because when we’re afraid of things, we try to cope by finding some humor in them. In high school, we watched Congress vote down even the most incremental increases in gun regulation as parents from Newtown, Connecticut, stood silently in the gallery and our president cried tears of anger and frustration. For two decades our leaders have failed us.
