Gravelly voiced conspiracy theorist Alex Jones touts himself as one of the few daring souls willing to tell the “truth” about 9/11 being an inside job, the Federal Emergency Management Agency’s plans to intern dissidents in “death camps,” and the “New World Order” plot to exterminate 80% of the world’s population. The Austin, Texas-based radio host suggests that he is a lone voice “in the wilderness” of a corporate media too cowardly to tell the truth about looming disaster.

But at least one member of that media has shown Jones nothing but love. Judge Andrew Napolitano, senior judicial analyst for Fox News and host of the Fox Business program “Freedom Watch,” calls Jones a “dear friend” who is “doing more than anybody I know” to “educate the public” with “courage and fearlessness.” Jones responds by calling Napolitano the “best person” on national TV. Last Friday, according to liberal watchdog Media Matters for America, Napolitano was on Jones’ show for at least the sixth time, and promised to soon bring Jones on to “Freedom Watch,” which he announced was expanding from the weekend to weekdays.

Maybe they’ll get a chance to discuss a Jones theory that’s a little more racially charged than much of his usual fare: a purported secret plan on the part of undocumented Mexican immigrants to murder all whites over 16.

Jones has been railing on about the so-called Plan de San Diego since 2005, when he began to talk about the genocidal plot by radical Mexican immigrants — a “Hispanic Klan,” in Jones’ words — to start a race war against U.S. whites. As Jones described it then in his “Nightmare Racism and Open Call for Revolution” blog post, he found out about the plot at an Austin event where a number of Latinos were wearing “Plan de San Diego” T-shirts. A group of Jones’ unnamed pals — including a “Hispanic friend,” a Spanish-speaking University of Texas professor and someone “who has taken Latin-American studies” — told him the rest: A “powerful revolutionary core” of “extremist Mexican hate groups” is currently “dedicated to overthrowing Texas and setting up a racial state.” Jones did not name the groups.

Buzz about the purported conspiracy is still making the rounds today. It’s hit the message board of Stormfront.org, the world’s premiere white supremacist website; bounced to a racist Facebook page calling for the boycott of Robert Rodriguez’s movie “Machete,” and showed up on the nativist hate site VDARE.com.

In his September 2005 blog post, Jones claimed that a third of the Latinos he spoke to at the Austin event “said that Texas was [part of] Mexico and that they were taking over.” Some, Jones claimed, even said that “all whites would be killed and that the entirety of the Americas would be only for ‘indigenous peoples.’” Jones doesn’t explain why the people he spoke to would share all of these details of the anti-white conspiracy with an obvious Anglo.

As it happens, there was a real Plan de San Diego. But it emerged from a Monterey, Mexico, jailhouse in 1915, during the Mexican Revolution of 1910-1920. The plan called for Mexicans to kill whites over 16 in Texas, which had been part of Mexico until 1848. Several dozen U.S. citizens were murdered, but the U.S. hit back hard. A 1919 Texas legislative inquiry found that between 300 and 5,000 Mexicans were killed by the Texas Rangers, an elite police force, in retaliation.

And that was the end of that.

What Jones later described as the “illegal alien rally” in Austin where he learned of the purported Latino conspiracy was actually a Mexican Independence Day celebration. If anyone there was wearing a Plan of San Diego shirt, it was at worst a statement of nationalistic pride in a lost cause, basically akin to a Confederate flag T-shirt. Poor taste bordering on the offensive, yes, but hardly a coded call to arms.

And the “frothing and screaming” Jones says he encountered at the hands of the Latino celebrants? Jones brought a bullhorn and a crowd of “Texans for Freedom” — an antigovernment group he heads — “to educate other well-meaning celebrants” of Mexican Independence Day about the “racist groups that were preaching their message in the Hispanic community.” The “well-meaning celebrants,” apparently, did not welcome Jones’ message.

So far, Jones’ main platform has been his radio show and two Internet websites. But now, thanks to Napolitano, that may be changing. In a March 2009 appearance on Napolitano’s “Freedom Watch,” which then was only on Foxnews.com, Jones expressed appreciation for the Fox website’s decision to have him as a guest. “Thank you, Fox,” he said, “you guys are getting radical having me on over there.”

It isn’t clear if Napolitano knows about Jones’ ideas about a murderous Mexican plot to kill whites and bring Texas back into the Mexican fold. But last Friday, on Jones’ show, he did bring up the topic of Texas secession. “Guess what?” he told Jones. “That time has come. That may actually happen.”
