On the one hand, I agree, deport illegal aliens, kids or no kids. However, given the fact the kids are US citizens coupled with thhe fact that trying to deport the parents of American citizens would be almost impossible in today's political climate...I'm not sure what the answer is...(other than seal the friggin border so they don't get here in the first place).
The reality of the situation is that sometime in the future the US will eventually absorb Mexico. The Southwest US is not going to 'secede'; rather, the tens of millions of Mexicans who have become Americanized will move to annex their former country.
