On Saturday, I marched with millions of others across the country in the March for Our Lives. March for Our Lives was organized by the students from Marjory Stoneman Douglas, the high school in Parkland, Florida, that was the location of a massive school shooting last month.

Seventeen Parkland students, in addition to several staff members, were killed when a former student shot an AR-15 across the campus. Since the shooting, several MSD students who survived the attack have taken a hard stance for gun control in the U.S.

These students, dubbed the “Parkland teens,” have participated in town halls and been an active voice for change, especially as another school shooting in Maryland claimed the life of yet another student.

The mantras of the March were “Enough is Enough” and “#NeverAgain,” messages that hoped this march would bring the necessary change to avoid another such catastrophe. The Parkland teens marched in their Florida hometown, others marched among a massive group in D.C., and several hundred of us marched from the City Deck in downtown Green Bay to the Brown County Courthouse.

The call was for the lives of students to be protected from gun violence, especially in schools, through common sense gun control, including measures like increased background checks, raising the legal age to buy a gun, and banning military assault rifles like the AR-15 (the weapon used in most of the mass shootings over the past few years).

At the Green Bay March, it was bitterly cold but the group was full of energy. The March had been organized by a dedicated group of area high school students.

Many local government officials spoke. A fourteen-year-old from Shawano shared her experience lobbying for gun control with a politician who belittled her and refused to take her seriously. An English teacher from De Pere High School gave a passionate speech about his overwhelming fear of protecting his students being a distraction; the speech brought me to tears.

Everything I experienced at the March was imbued with an overwhelming call for change. Students, teachers, and administrators today are filled with an unnecessary fear as these tragedies occur almost monthly. From Columbine to Sandy Hook to Parkland, children are being killed while little to no governmental action has been taken to prevent further tragedies.

It seems clear to me that America has a gun problem, and it’s time to take action with simple gun-control measures. Just like you can’t shout “fire” in a movie theatre despite our right of free speech, the second amendment requires limitations for our basic safety and protection.

After all, we are marching for our lives.
