First and foremost, you want a simple answer? Lets ask first and second generation Hispanic, and Mexican citizens what they feel should be the best choice for America. I would think of anyone, they could probably base their decisions with more understanding, and real-life experience then any of us decade old descendants of immigrants could understand.
The plain and simple fact is this. When people state their opinion, they often don't consider humanity. Or should I say being humane? Let me ask this, of any of us natural-borns.... If I told you, at this moment your wife, or husband had to return to where-ever your family descended from, but you and your children could stay, what would you do? What if your here illegal, and your children were born here. What if Mexico won't accept your children, and yet America won't accept you? I don't care who you are, and what you currently think you know... You would without a doubt would have your life destroyed by this law.
Sure you want to say, well we have to end illegal immigration right? No what we need to do is be good neighbors to our Mexican friends and do whatever we need, despite its cost to take care of one another. We are not animals, we do not need to be king of the mountain, or be the last man standing. It's not the Mexicans that people fear, but that we, as the richest, fattest, most possession rich country in the world's history, might have to give something up in order to lend a helping hand to our brothers and sisters.
Just remember this, in the next life it could be you being born on the other-side of the immigration fence.
