“Open borders” is a straw man. Nobody advocates that.

Oh, really? I do.

The anti-labor and racist effects of giving government the power to discriminate against peaceful workers, based solely on their nationality, should be obvious. If self-identified Progressives are not willing to oppose, on principle, the government’s surveillance, stopping, stamping, recording, searching, restraining, beating, jailing, and exiling peaceful workers who have never done anything to violate anybody else’s rights, based solely on those workers’ nationality and an arbitrary government-imposed quota, then so much the worse for Progressivism.
