An Argument Against Open Borders and Liberal Hubris by Ben Sixsmith.
No one except a militant nativist would deny that some level of immigration is beneficial and should be accepted. After that, we face a question of scale.

These are advocates of “open borders”; an idea as strange as that of the nativist—yet more dangerous for being considered respectable.
