I am not completely endorsing the Bishop's position, but I recognize too that the Bishop is not attempting to set policy, but rather to shape it. In doing so one must often exaggerate and over state ones position.
But lets not deceive ourselves into believing that we are innocent victims in this matter, intentionally targeted and abused by a hoard of uninvited immigrants. We as Americans share much of the blame for creating and fostering the conditions that lead to the current state of affairs. We as Catholics have an obligation to deal with the human consequences regardless of the causes and blames.
An insane drug policy that ignores the lessons of Prohibition, coupled with an insatiable demand for drugs in this country has created conditions south of the that no sane human would wish to endure or let alone attempt to raise a family. The popular culture here that thinks drugs are cool and that drug use is a victimless crime is an accomplice in the violence in Mexico.
The demand and tolerance for cheap, off the books labor, whether by businesses or by individuals looking for a nanny, construction workers, or crop harvesting is creating an attractive nuisance. This coupled with open borders and a catch and release immigration policy provides no disincentives. Lastly our welfare policies and freebies as a result of both political parties looking for new voters has resulted in a very large problem.
I do not blame the illegals as much as I blame the hostile US elite who are intentionally targeting and abusing the American people. Importing cheap labor has displaced blue collar Americans on a massive scale. Large-scale non-European immigration creates social division aimed at short-circuiting any revival of nationalism in defense of American interests.
Unfortunately, many bishops are siding with liberal elites against the interests of American Catholics. Dissolving American borders has nothing to do the traditional Catholic teaching. The bishops of Latin America would never betray their people in this way.
