Citizenship required

Attempts to equate contemporary immigration law enforcement with discrimination against 1930s German Jews and civil rights-era American blacks are crippled by a logical flaw. 

In each historic instance, already-legal citizens of those nations were denied rights they were due by virtue of their established citizenship. Martin Luther King, Jr, for example, argued persuasively that the US government needed to live up to promises our constitution makes to citizens. He didn't advocate for anything new, only that the traditionally accepted be ensured for all Americans.

Non-citizens outside US borders do not have legitimate claims to protections under our constitution. For that reason, they are not at all similar to Germans or Americans who were previously, wrongly denied protections and liberties guaranteed them by their respective countries.

Persons now calling for no enforcement of immigration laws and for open borders are endorsing the radically different notion that there is no distinction to be recognized between citizens and non-citizens.

Their argument is a globalist one. It shares no ground with Anne Frank or Rev. King, and is hostile to the concept of national sovereignty.
