The libertarian Cato Institute has emitted their latest "Handbook on Policy."

From the immigration chapter:

To better defend ourselves against terrorism and promote economic
growth, America's border-control system requires a reorientation of mission.
For the last two decades, U.S. immigration policy has been obsessed
with nabbing mostly Mexican-born workers whose only ''crime'' is their
desire to work, save, and build a better life for their families. Those
workers pose no threat to national security.

Yes, the quotation marks are there in the original. And, yes, the rest of it is just as bad if not worse.

(For those just joining us, allowing a foreign country which used to own part of our country to resettle its old territory is a really bad idea. In addition, massive immigration from one country leads to more power for racial ideologues. I'm sure there are some libertarians who would consider that a clear "threat to national security."
