Mark Krikorian, head of the Center For Immigration Studies,  has been triangulating against VDARE.com and others to his right for years:

Are you now, or have you ever been, a “hate group”?

This is the question at the heart of an attempt to delegitimize and suppress views regarding immigration held by a large share of the American public

Here, Mark is triangulating against Senator McCarthy, HUAC, and other anticommunist patriots of the Fifties—but let that go.

Since 2007, the Southern Poverty Law Center has methodically added mainstream organizations critical of current immigration policy to its blacklist of “hate groups,” including the Federation for American Immigration Reform, the Immigration Reform Law Institute and Californians for Population Stabilization, among others. In February, my own organization, the Center for Immigration Studies (CIS), got its turn.

How labeling my organization a hate group shuts down public debate, By Mark Krikorian, March 17, 2017

The SPLC labeled us a hate group in 2004. I'm not sure why we're less mainstream than CIS—could it be because we're less well funded?

Krikorian also triangulates against the great  Dr. John Tanton:

The rationale offered for CIS’s inclusion on the blacklist is implausible even for those predisposed to support blacklists. The SPLC long ago made a hate figure of John Tanton, a controversial Michigan eye doctor it breathlessly describes as the “puppeteer” of various groups skeptical of current immigration policy, including CIS. But whatever his vices and virtues, they are irrelevant to CIS; as he himself has written, “I also helped raise a grant in 1985 for the Center for Immigration Studies, but I have played no role in the Center’s growth or development.”

Then he triangulates against his own   CIS staffer (Jason Richwine) his own CIS non-resident fellow (John Miano) and of course VDARE.com.

Why CIS should only now qualify for the blacklist is something the SPLC offered no explanation for. Only in a blog post by America’s Voice, an allied group, were SPLC spokesmen quoted explaining how CIS meets their “rigorous criteria for designating organizations as hate groups.” Judge the rigor for yourself. Reason one: CIS has published work by independent researcher Jason Richwine, who wrote a contentious Harvard University dissertation on IQ a decade ago. (His work since has been on other subjects.) If this is evidence of “hate,” then the SPLC is going to need a bigger blacklist; other places that have published Richwine’s work include Forbes, Politico, RealClearPolicy and National Review, and his co-authors have included fellows at the American Enterprise Institute and New America.

Reasons two and three are almost too trivial to believe: CIS’s weekly email roundup of immigration commentary (from all sides) has occasionally included pieces by writers who turned out to be cranks; and a nonresident CIS fellow attended the Christmas party of a group the SPLC dislikes. Seriously, that’s it. (Emphasis added)

Lets unpack that—the America's Voice post includes an interview with Heidi Beirich, who explained her

CIS has a long history of bigotry, starting with its founder, white nationalist John Tanton, but in 2016, the group hit a new low. CIS commissioned Jason Richwine, a man who’s PHD dissertation endorses the idea of IQ differences between the races, to write multiple reports and blog pieces for the organization. The group also continued to circulate racist and anti-Semitic authors to its supporters and finally, staffer John Miano attended the white nationalist group VDARE’s Christmas party in December.

SPLC Annual Year in Hate Report: Center for Immigration Studies Is A Hate Group, February 15, 2017 (Emphasis added)

It was very decent of Krikorian to give Jason Richwine a job after Heritage fired him, but it's also clear that he doesn't want him to say anything about the low IQ of modern immigrants.  That was more or less the subject of Krikorian's 2008 book The New Case Against Immigration, but Krikorian triangulated there, too.

As for John Miano, co-author with Michelle Malkin of Sold Out: How High-Tech Billionaires & Bipartisan Beltway Crapweasels Are Screwing America’s Best & Brightest Workers , he was not only at the Christmas Party (something they learned from Radio Derb) he thanked VDARE.com editor Peter Brimelow in the acknowledgements of Sold Out.

Krikorian's experience with the SPLC is the classic case of "paying the crocodiles to eat you last." Now that people like us, not Krikorian, have got Trump elected, some of CIS's staffers will be working for the Administration. The SPLC objects to that, too. Krikorian's basic mistake was to accept the SPLC's premise that some patriots were too extreme to associate with.

This is the result.
