Updated at 6 p.m., June 11, 2018: with comment from Open Carry Texas founder CJ Grisham.

Open carry activists are planning a rally in Santa Fe next weekend, a month after a deadly shooting at the town's high school, to demonstrate support for arming teachers.

The Facebook event page for the "Carry for Our Kids" rally features an advertisement with children playing on top of a black and white pistol.

The rally is planned for 10 a.m. June 23 at Runge Park, a five-minute drive from Santa Fe High School, where a 17-year-old student opened fire with a shotgun and pistol he took from his father, killing eight classmates and two teachers.

The school shooting in the small town near Houston was the nation's deadliest since the shooting in Parkland, Fla., when 17 people were killed.

"How many more innocent children need to die before we wake up and prepare our teachers to fight back?" the Facebook event description reads. "The only solution is self-responsibility: Arm school officials and give them a fighting chance. No gunman is going to target a school that can defend itself and fight back."

The rally is organized by Open Carry Texas and Texas Freedom Force, a gun rights group that made headlines last year for defending Confederate monuments from protesters in several Texas cities. Open carry activists, including Open Carry Texas founder CJ Grisham and James Dickey, chairman of the state GOP, are expected to speak.

Days after the Santa Fe shooting, Gov. Greg Abbott held a three-day summit to discuss suggestions for ending gun violence in the state's schools. Some of the policy options that made their way out of the roundtables include providing better training for teachers who want to be armed school marshals and expanding the program so it's available to "every school at every level."

Offices for the governor and lieutenant governor have not returned requests for comment.

Advertising for the rally began circulating on Twitter on Monday afternoon, as some called it insensitive to have a demonstration with protesters openly carrying guns so soon after the school shooting in the same town.

Manny Garcia, deputy executive director of the Texas Democratic Party, tweeted screenshots of the rally's Facebook event page, tagging some of the state's leadership, including Abbott and Sen. Ted Cruz, and asking if they "care to comment."

Garcia told The Dallas Morning News that the planned demonstration shows an "utter lack of empathy," adding that as mass shootings continue to happen, "It's important for us to have real, substantial conversations about stopping gun violence that includes the very common sense things we can do to keep guns out of dangerous people's hands."

“It’s sad that this is a state that’s accepting these kinds of school shootings as sort of inevitable," he said. "And that’s the tone and direction our state leadership is showing, to act like these instances are inevitable, rather than taking preventive measures to ensure they don’t happen.”

Grisham disagreed, saying it's no more "insensitive" than holding a protest against open carry laws.

"Holding a rally in favor of gun rights is no more insensitive that holding a rally against gun rights," Grisham said. "Gun rights activists will not be cowered by the liberal narrative that seeks to shame gun owners out of defending life and liberty."
