I posted the following earlier on a personal blog, so it doesn't have full citations or any sort of formality. Nonetheless, it's worth debating over.

1.  Humanitarian aid is sometimes a crime.  Aiding and abetting crime is not only illegal, it's unbiblical.  We know that from Romans 13.  Jesus commands us as Christians to help the less fortunate, and this is no exception.  The organization that best exemplifies this example is...The Minuteman Project!  They obey our laws, and they get the Border Patrol to people who need food and water.

2.  The purpose of government is not to do the 'Christian' thing when something like this comes up.  2 Corinthians 9:7 states "Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver."  Giving is not the responsibility of government; it is our responsibility.  Imagine what happens when we give the government the power to determine what is the 'Christian' thing to do.  That what we like to call theocracy, and we can't have anything near that.

3.  I read in a political science textbook the other day one commentator's opinion that "The relative difference between this and other waves of immigration is that these immigrants want to share in the distribution of the nation's material goods, but they are hardly interested at all in identifying with the political values of the same community."  People who desire to live in our country must identify with our political values.  That doesn't mean adopting the American 'apple-pie and baked potatoes' culture; it means respecting the rules of civil discourse and taking personal responsibility.  When illegal immigrants force hospitals (read: patients) to pay for their health care simply by virtue of having crossed the border, and when students of Mexican descent hang Mexican flags above upside-down American flags, I get a little worried that the population has not adopted our political values.  That in itself is a generalization, sure.  But above all, respecting our political values means not breaking the law, which by definition every illegal immigrant has done.

4.  We could argue the economics of the debate all day.  As I am not an economist, I don't want to go too far into that; this is the politics.  If Mexican workers are an economic necessity (and by no means am I saying they are), then let's make it easier for Mexicans to work in the United States, whether that be via guest worker programs, accelerated citizenship, etc.  Don't circumvent law in order to fit circumstance.
