Victor Davis Hanson on borders and the lack thereof:
Among elites, borderlessness has taken its place among the politically correct positions of our age — and, as with other such ideas, it has shaped the language we use. The descriptive term “illegal alien” has given way to the nebulous “unlawful immigrant.” This, in turn, has given way to “undocumented immigrant,” “immigrant,” or the entirely neutral “migrant” — a noun that obscures whether the individual in question is entering or leaving. […]
What we might call post-borderism argues that boundaries even between distinct nations are mere artificial constructs, methods of marginalisation designed by those in power, mostly to stigmatise and oppress the “other”… “Where borders are drawn, power is exercised,” as one European scholar put it. This view assumes that where borders are not drawn, power is not exercised — as if a million Middle Eastern immigrants pouring into Germany do not wield considerable power by their sheer numbers and adroit manipulation of Western notions of victimisation and grievance politics. Indeed, Western leftists seek political empowerment by encouraging the arrival of millions of impoverished migrants.
Inevitably, the issue of naked, often comical hypocrisy becomes hard to avoid:
Facebook founder Mark Zuckerberg offers another case study. The multibillionaire advocates for a fluid southern border and lax immigration enforcement, but he has also stealthily spent $30 million to buy up four homes surrounding his Palo Alto estate. They form a sort of no-man’s-land defence outside his own Maginot Line fence, presumably designed against hoi polloi who might not share Zuckerberg’s taste or sense of privacy. Zuckerberg’s other estate in San Francisco is prompting neighbours’ complaints because his security team takes up all the best parking spaces. Walls and border security seem dear to the heart of the open-borders multibillionaire — when it’s his wall, his border security.
