This matter of undocumented immigrants, does it matter to some of us because they are here illegally or because they are "brown" and of a different culture? Europe is a pretty decent place to live and many Europeans don't want to come to America to clean motel rooms, toilets, and change beds - not to mention every other job these undocumented workers are willing to do. We need to accept this fact, that legal or illegal, it's not going to be Europeans picking strawberries here for us.
"They" are going to be here legally or illegally. Once they are forced to obtain proper documentation, then what excuse are we going to use to send them back? Do you really want them to have "papers"? Many with proper documentation will not wish to return back home as most with no documents now wish to do.
