If you don’t curb guns, we’ll vote you out

Lynn Parr, a kindergarten teacher at Public School 333, said it sickens her to hold school drills where she has to lock her classroom and explain to 5-year-olds why they must stay silent.

“I assure them they’re safe,” said Parr, 47. “The truth is no one is until something changes.”

Not everyone was advocating for more stingent gun laws. A small group of counter-protesters showed up wearing NRA hats and holding signs that read “Keep America Armed.”

“I don’t think people understand our side of the issue and the gun culture,” said one counter-protester from Brooklyn who identified himself as Jonah. “I don’t believe gun control is productive, or that it works.

But the gun-rights proponents were mostly drowned out by the voices of the majority.

Near the Museum of Natural History, four young girls climbed atop a metal barricade and started shouting, “This is what democracy looks like.”

A group of Brooklyn kids ages 6 to 11 had implored the leaders of their afterschool program to allow them to participate in Saturday’s event.

“They watch the news. They hear things. They’re like a sponge,” Iviarra McLaughlin, of the University Settlement Society of New York, said of the students from Public School 219 in East Flatbush.

“Every day they talk about how scared they are — how they want to make a difference.”

Jared Hecht, 31, traveled to Manhattan with his wife Carrie and year-old son Elijah, and said he was sickened by the seemingly endless barrage of school shootings in America.

“Kids are getting shot in school every single day, every single month, and that’s not normal,” he added.

“Nor is it acceptable. Kids are the ones who started all this. I don’t think it would be here today if not for the Parkland kids putting us on a path to seeing change happen.”

Four freshmen from the Trinity School on the Upper East Side — Mina Zanganeh, 15; Sam Chachkes, 15; Naomi Doron,14; and Kyra Siegel, 15 — joined the throngs of protesters.

Following the Feb. 14 mass shooting in Parkland, Fla., they formed their own antigun violence group.

“I remember thinking so clearly, that could have been us,” said Mina.

“We’ve always been told we’re the future. We’re the present, too.”
