I am not persuaded by Zaid Jilani's argument about immigration

This piece by Zaid Jilani at Persuasion suggests that both the right and left have a mistaken impression of immigrants, but only makes the case halfway. Let's start with the headline:

Well, surely at a publication named Persuasion, Jilani will back up this assertion with some evidence, right?

Kind of.

Fearmongering about the ways in which immigrants will transform America is a hallmark of the conservative movement in the age of Donald Trump. Ann Coulter, the far-right provocateur, recently warned that “legal immigration is going to destroy this country.” The more moderate Hudson Institute has claimed that the country’s “patriotic assimilation system is broken.” Even Amy Wax, a professor at the University of Pennsylvania, has argued for a “cultural distance nationalism” which effectively leads to the conclusion that “our country will be better off with more whites and fewer non-whites.”

Makes sense. Now, as for the left?

Despite their righteous defense of immigrants, many leftists share a remarkably similar view: they too assume that most immigrants are antagonistic to American culture. Trying to appeal to a group of immigrants in Tennessee during his abortive run for the presidency, for example, Beto O’Rourke told them that “this country was founded on white supremacy. And every single institution and structure that we have in this country still reflects the legacy of slavery and segregation and Jim Crow.” Like O’Rourke, many left-wing activists simply assume that immigrants will be sympathetic to a worldview that describes America as a “failed social experiment.”

Now: It's unfair perhaps to ask a paragraph to make an expansive case for an idea. But Jilani did a pretty good job with conservatives, selecting four examples of people and institutions that are influential among conservatives.

With the left, though, he found ... one comment from a failed presidential candidate. And that statement doesn't tell immigrants not to be patriotic! It just offers a pretty typical left-of-center argument about the history of this country. The Cornel West quote Jilani offers has nothing to do with immigration, either. 

Basically, Jilani just assumes the left is unpatriotic. He bases this more on his own college-era reading of Noam Chomsky than anything else. Perhaps it depends on your definition of patriotism -- if it includes "turning a blind eye to America's sins," as a lot of conservatives seem to think, maybe he's right. But I suspect this is just false evenhandedness -- both conservatives and liberals are wrong! -- in the name of trying to ... persuade. But that actually makes it unpersuasive.
