Besieged by grief after the devastating and terrifying carnage at Marjory Stoneman Douglas High School in Parkland, Florida, the children-students have become the adults in the conversation. They say it isn’t too soon to talk about gun control. They say they are tired of inaction on the part of politicians and the government. They say children should not be afraid to go to school. They say it’s time to do something to prevent school shootings.

And perhaps those who have a responsibility to take action are listening. Perhaps the very poised, articulate, and rightfully angry students of Douglas High have themselves taken the first step to fix the problem.

The truth is the “problem” experienced in Parkland, Sandy Hook, Columbine and other schools is complicated. Everyone has an opinion—too many guns, too easy to get an assault rifle, too many troubled teens or adults, and on and on. Consequently, there is no simple “fix.”

But the students who raised their voices and gained the attention of the nation—maybe the world—have expressed the right idea. Now is the time to begin the conversations, to take the steps, to do whatever is necessary to prevent this type of tragedy—whether in a school or in a concert hall—from happening ever again.

As I listened to the students, teachers, and parents speaking to the President in the White House recently, I was extremely proud of this next generation. In the midst of much of turmoil and division in the world, they represent hope for the future. I was also impressed with other grassroots programs which sprung from the tragedies of Columbine and Sandy Hook and now bolster the movement roused by the most recent school massacre.

The powerful crusade energized by the Parkland students is less than two weeks old. Hopefully, this daunting campaign will strengthen and endure. There’s a lot of work to do, but the first giant step has been taken by some very brave teenagers.
