First we need to agree that the term "illegals" is referring, in large part, to people who otherwise have done nothing to be considered a threat to the public. That if we were born in the squalor they were, we'd probably be here illegally as well. Once we do that, we need to agree that these are human beings, not pieces on a chess board separated by imaginary lines.
Ok, now we've done that, we need to decide if the plight of people from other countries, even bordering ones, are more important than our own. We need to prioritize our own issues. Getting new computers in your local school could be more important to you than the fact that several families who weren't born here could perish in the desert while trying to get here so they can survive. We need to find a way to make coming to the US easier. We need to put our resources in immigration, not against it. We need to not equate all immigration with illegal immigration, and not equate illegal immigration with home intruders.
