Stefan Molyneux, a video blogger popular with far-right and alt-right audiences, claimed that it was actually “political correctness” and not loose guns regulations that enabled the mass murder of 17 people at Marjory Stoneman Douglas High School in Florida last month.

In a video uploaded yesterday, Molyneux sought to break down what he believed to be “the ugly truth” about the March for Our Lives protests on Saturday, which attracted hundreds of thousands of people across the United States to stand with survivors of the shooting who demanded gun reform measures aimed at making schools safer.

“Now, of course, the proximate cause for all of this was the shooting in Broward County recently—the shooting of the children. And because there is an emotionally reactive group of people who either have never been exposed to the facts and the truth about that shooting, about guns as a whole, or simply have simply ignored it if they have been exposed to it, or they’re simply useful happy bleating idiots—the puppets of the puppet master—speaking out against the elemental freedoms of the United States,” Molyneux said.

“The fact is that it was not fundamentally a gun that killed those kids in the school in Florida. What killed those kids was political correctness,” he said. “What killed those kids was political correctness.”
