It’s a vile conspiracy theory we might expect from the host of Inforwars Alex Jones, but right now it is the number one trending video on YouTube.

The conspiracy theory is that some of the students who are speaking out against the lax gun control laws that enabled the mass shooting that killed 17 of their peers at a Parkland, Florida high school last week are not who they say they are. They are “crisis actors,” paid performers funded by familiar boogeymen like George Soros to vilify gun ownership and dismantle the Second Amendment.
