Note: Given some discussions I have had, I suspect that some libertarians will object to DiLorenzo's view as being anti-libertarian, But government directed, financed and escorted immigrants to areas where no one wants them is not libertarianism. It is the evil state infiltrating deeper into the fabric of society. To turn a blind eye to this and proclaim "open borders are good" misses the fact that this is not a simple case of open immigration but a package that delivers with it forced support by the state that many may not want to have anything to do with.
Indeed, it appears that it is an effort by the state to breakdown relatively private communities for the advancement of the state. It is, as DiLorenzo correctly writes, a state-led attack on Western Civilization.
