The primary rationale used by a significant minority of our population to justify legalizing those who have deliberately violated our immigration laws by breaking into our country, is that they're doing jobs Americans won't do. They pick our fruit, mow our lawns, wash our cars, clean our houses and cook for us when we eat out, so they should be welcomed. And warmly. They're really nice folks, this group's thinking goes, and therefore they shouldn't be punished for willfully ignoring our borders and breaking our laws.
Using this same rationale, it seems to me we should all be applauding Arizona for passing SB 1070, a law intended to try to do for itself what the President, the Attorney General, the Secretary of Homeland Security (who, interestingly, used to be Arizona's Governor), the Justice Department and the Administration as a whole have blatantly chosen not to do; secure our borders and enforce our Federal immigration laws. The fact that the aforementioned public officials are sworn to uphold these laws, and don't, apparently means nothing to the pro-illegal immigration crowd. Or, to the vast majority of the mainstream liberal media, for that matter.
So. to be perfectly consistent, a goal to which every fair-minded individual should aspire, it looks to me like this: Illegals: Doing the jobs Americans won't do. Arizona: Doing the job America won't do. Kind of has a ring to it, don't you think?
