The song is "Make It Stop (September's Children) by Rise Against. I love the message in this song, even though the song itself isn't my favorite.

Bang bang go the coffin nails

Like a breath exhaled

Then gone forever

It seems just like yesterday

How did I miss the red flags raise?

Think back to the days we laughed

We braved these bitter storms together

Brought to his knees he cried

But on his feet he died

What God would damn a heart?

And what God drove us apart?

What God could

Make it stop?

Let this end

Eighteen years pushed to the ledge.

It's come to this

A weightless step

On the way down singing

Bang bang from the closet walls

The schoolhouse halls

The shotgun's loaded

Push me and I'll push back

I'm done asking, I demand

From a nation under God,

I feel it's love like a cattle prod

Born free, but still they hate

Bore me, no, I can't change

It's always darkest just before the dawn

So stay awake with me, let's prove them wrong

Make it stop

Let this end

Eighteen years pushed to the ledge

It's come to this

A weightless step

On the way down singing

The cold river washed him away

But how could we forget

The gatherings hold candles

But not their tongues

And too much blood has flown from the wrist

Of children shamed for those they chose to kiss

Who will rise to stop the blood

We're calling for,

Insisting on

A different beat, yeah

A brand new song
