Oh... I get it now.
You believe the bullshit that was fed to you in civics class - that laws are absolute.
In that case there is no problem with abortion, right? Law says its OK, right? People going over the speed limit, even by 1mph, deserve to be ticketed, right? Smoking pot is illegal and wrong and that's why ~everyone~ who uses pot is punished, right?
Funny how the "but its the LAW!" outrage generally only comes up when a law that ~you~ like isn't being enforced they way you want it to. Many laws are only absolute for those too timid to find the gray area at their edges.
Far - and I mean FAR - more laws are passed than can be, or are meant to be, fully enforced. Politicians, police, enforcement agencies, businesses and private citizens the world over play in the gray area between what is legal and what is enforced. They do so according you their local, personal and political goals. Why this is surprising and shocking to you is beyond me. This is politics and business as usual.
But, as I first stated when I waded into this topic, I agree that the law ~should~ be followed. If the law is unenforceable or if enforcing it would have undesirable consequences then it should be changed - then enforced. In the absence of that clarity it gives rise to silly situations like this where both sides use the gray area for divisive political gain without having to actually address the issue and resolve it.
But in the case of illegal immigration there is no resolving it - not if your idea of resolving it is stopping it. The issue has never been stopped humanely in the history of civilization when you have a very rich country next to a very poor country. Ever. Anywhere. Not once. Do you understand what I'm saying? NEVER. In all of history. Ever. Its not as simple as passing a law and enforcing it - your beliefs on the issue not withstanding.
So either you get used to and find ways of dealing with a growing illegal immigrant population or you get used to the idea of an increasingly militant police state. Take your pick. So far I agree with erring on the side of freedom.
They didn't mention this kind a stuff in Civics class.
