Punish those who break our laws, not innocent family members.
Immigration law exists
only for the benefit of the U.S. as a whole and for its citizens in particular. As wealthy as we are, our economic and sociopolitical resources are still limited. It is the government's job to maximize the security and quality of life
for its citizens. The immigration laws are designed to select for good visitors--not sickly, criminal, illiterate, unskilled folks who cannot support themselves. There may be situations in which it is in our best interests to take in refugees with only emergency-level screening (e.g., freedom-loving Christians who are being persecuted to death by, say, consistent Muslims).
Certain refugees would make wonderful, productive, grateful citizens of our great nation--but it is a well-documented fact that certain kinds of immigrants plan only to exploit or even deliberately ruin our Republic. Even a shockingly high percentage of the Muslims already in our country--whether naturalized or not--advocate implementation of Sharia law and even quietly condone violence to that end.
Many folks who have been in the U.S. for decades have never cared to become citizens, never learned English, and never bothered to understand our Constitutional Republic. This is a huge problem in California, in which 27 percent of the state's residents were not born in America. That is likely the main reason why the state votes Democrat. (Voting fraud is evidently rampant in California, by the way.)
Under these circumstances of a badly messed up, even hostile world, it is a slow-but-sure national suicide deliberately facilitated by Global Socialists (the very real, very determined, very dangerous enemies of our sovereign nation) to have only a loose immigration policy (for example, an open borders policy).
Americans as a whole have always believed it is good to do good, and Americans rank among the most charitable people in the world, but self-righteous, power-mad politicians must never overrule its own citizenry's best interests in the interests of Globalism. And saying that we must not punish innocent victims is completely beside the point. The deportation of folks who came to the USA illegally is not punishment. It is a necessary defense of American law, of American sovereignty.
