The Ceaseless Importation of Third World Foreigners With No Taste for Liberty (Part 2)

“The ceaseless importation of Third World foreigners with no tradition of, taste for, or experience in liberty means that the electorate grows more left, more Democratic, less Republican, less republican, and less traditionally American with every cycle."

A 22-year-old undocumented immigrant arrested by Immigration and Customs Enforcement in Jackson, Mississippi, on Wednesday after speaking to the media about her family’s detention, is set to be deported without a court hearing, her attorney said on Thursday.

Daniela Vargas, who came to the U.S. from Argentina when she was 7 years old, previously had a work permit and deportation reprieve under the Deferred Action for Childhood Arrivals program, or DACA. Her DACA status expired last November, and because she was saving money for the renewal — which cost $495 — her new application wasn’t received until Feb. 10.

If Trumpista worries about immigration were truly about liberty and "culture" you'd think that something could be done about the so called "Dreamers" — adult immigrants brought here as children — short of deportation. After all, these are a group of people largely raised as Americans;  they have spent lives immersed in our country and its traditions, and they do have the taste for and experience of American variety of liberty. With rare exception, they are assimilated.

So why is it so important to deport them? Why the resistance to any legal framework that lets them become citizens?
