Don't walk up OR walk out. Break out.
Students at Concord’s Mt. Diablo High break through gate in gun protest
Lately I've seen friends on both sides of the "Walk Out/Walk Up" debate. The two sides are (roughly)
1. Instead of walking out to protest guns, kids should walk up to the weird, bullied kid and befriend him. 2. It's not any kids responsibility to be nice to anyone in order to not get shot.
Neither of these does anything but anger the other side, and both completely miss the root cause.
With public schools being prison-like environments, the incentives on children are to be awful to each other. This will not change until adults do something to make schools less like prisons, and no amount of shootings will change that. Neither will scolding kids to be nicer. Anti-gun programs are useless bullshit. Anti-bullying programs are useless bullshit. All the permanent incentives that shape action are pushing children to emulate prison gangs.
The schools must be reformed. By adults.
