Conservative commentator Dana Loesch is hitting back at critics of a National Rifle Association advertisement in which she urges people to fight the Left’s “violence of lies” with the “clenched first of truth.”

“Look, it’s simple,” she tweeted on Thursday night, “Don’t destroy property and hit people while you’re rioting and I won’t condemn it in a video. It’s that easy.”

The NRA ad shows black-and-white video of left-wing activists rioting, smashing store windows and burning cars during and after the election of President Donald Trump. One clip shows a man in a Trump T-shirt sitting on the ground, with his head bloodied and bandaged.

“I am proud of this ad. I endorse personally the message of this ad, it’s a fantastic ad, and it holds up a mirror to the violent aspects of the Left,” Loesch said on Friday on NRA TV.

The ad was originally released in April but was re-posted to the NRA’s Facebook page on June 12 and suddenly got press attention this week when organizers of the so-called Women’s March called it “racist” and “extremely dangerous” and penned an open letter to the NRA, asking the organization to take it down.

Left-wing media were happy to join the fight.

Salon called the ad “violent” and “terrifying,” while Time magazine said even gun owners didn’t like it, quoting from a couple of Facebook posts.

Sen. Chris Murphy, (D-Conn.) tweeted on Thursday: “I think the @NRA is telling people to shoot us. Now might be the right time to cancel your membership.”

But the ad denounces violence, and calls for non-violence to defeat it.

It opens with Loesch looking directly at the camera and speaking forcefully:

“They use their media to assassinate real news,” she says. “They use their schools to teach children that their president is another Hitler. They use their movie stars, and singers and comedy shows and award shows to repeat their narrative over and over again.”

Videos begin to play, showing protesters in the streets, and then scenes of extreme violence, with a car going suddenly up in flames in one clip.

“And then they use their ex-president to endorse the resistance,” Loesch says as these scenes play, “all to make them march, to make them protest, make them scream racism and sexism and xenophobia and homophobia, to smash windows, burn cars, shut down interstates and airports, bully and terrorize the law-abiding until the only option left is for the police to do their jobs and stop the madness.”

The ad ends with Loesch exhorting law-abiding Americans to “fight this violence of lies with the clenched fist of truth.”

“We would never apologize for a video that exposes these radical liberal terrorists for what they are — anarchists who want to tear down this nation,” Grant Stinchfield of the NRA said on Friday on NRA TV.

“Facebook may cave — I wouldn’t be surprised if they do,” he said. “I hope they don’t, though, because there is nothing inciteful about Dana’s message. The inciting is what she’s calling out.”

“I’m not going to apologize for this video,” Loesch said. “In fact, I’ll double down on this video and every attempt to intimidate me and push me into silence. I’ll only get louder.”
