PS notice that the Evangelicals, Falwell, Robertson, have been extremely quiet about this issue that has turned into a crisis.
Yes, the leadership of the Christian Right has been quiet. But the chief intellectuals have not. Phyllis Schalfly and Cal Thomas have been spot on about this issue.
The key issue here is that Mexico's goal isn't simply to export its poor people to the American taxpayer. It is to create a pro-Mexican Fifth Column in American electoral politics (and never underestimate the level of irredentist anger in Mexican politics towards the US). And all those Mexican flags in those demonstrations make this very clear.
