Pro-Illegal Immigration: What will you say when time for excuses is over?

A radio commentator stated the pro-illegal immigration argument quite succinctly:

"Imagine if I spent money wildly on when I wanted to. I would just buy buy buy...anything I wanted to. My wife steps in and says that I should stop spendingg so much money, or else there could be a problem. I turn to her and say 'You don't want me to spend more money because you just want more for yourself!'. Then, one day, we run out of money."

This is akin to the pro-illegal immigration argument that's trotted out every time - "You think all illegal immigrants cause trouble, so you're a racist", in response to "The immigration laws need to be enforced".

Well, Mr./Ms. Pro-Illegal, I can't wait until the situation gets so bad that your little corner of the world is affected. Who will you blame and how will you pin it on them? Given the lack of rational thought you currently posses, I'm certain it will be at least one level of outrageous beyond your current "you're a racist" arguments.

I await with baited breath.
