DEMOCRATS ARE TURNING IMMIGRATION INTO A MORAL ULTIMATUM

Why have attitudes on immigration gotten so much more radical in recent years? Hint: It’s not just Trump.

Deciding who does and does not get to become an American has never been simply a matter of law. In the U.S., immigration has long been a social gospel as well a policy question; a balance of moral and practical considerations. We’ve come a long way since the bigoted nativism of early 20th century anti-immigrant crusaders, but in our own time it’s the moral mythologies of liberal Democrats that have become increasingly detached from practical realties. The traditionally pro-immigration Democratic Party has not simply become more pro-immigration in recent years. Rather, in a fairly rapid shift over the past two decades, the party leadership and faithful have adopted a radical new framework that treats any restrictions on immigration and enforcement of current laws as immoral.

Sensible immigration reforms and policies that long commanded the support of majorities in both parties are now decried as veiled racism. In their place, the progressive wing of the Democratic Party is pushing for an immigration vision that borders on open-borders advocacy. Three years into the Trump administration, some of the radicalization on the left is undoubtedly responding to the reports of deportations, squalid conditions in detention facilities and the increasing normalization of nativist rhetoric from the White House. But Trump is not the fundamental driver of this phenomenon, which started before he took office and fits into the larger pattern of “white saviorism” pulling the Democrats to the left. 

I think Democrats increasingly see all 7.5 billion Pre-American-Americans as a minority oppressed by the 95 million straight white male Americans.
