Is AZ's policy on immigration racist? I don't think the specifics are: the law as it is read. But let's take a look at immigration and the underlying ideas about it.
In order to support limited immigration one must believe that either, 1) immigration is somehow bad for the country, the economy, or yourself, and 2) that a persons worth is determined by where they were born, and that you, as an American are more worthy, more priviledged than Mexicans. That second part is the racist part.
What is the law, exactly? As of this 30 April 2010, it call for police in AZ to check the immigration status of anyone they have reason to suspect might not be in the country legally that they have stopped, detained, or arrested. (This is a change from earlier legislation.) It also makes it a crime for immigrants not to have their paperwork with them at all times.
I see a couple of problems with this, and some easy solutions to getting it taken off the books. What about if a Hispanic American citizen is walking around in public with no papers on them? This could get them arrested. This is clearly a violation of an American citizen's rights. Second, don't police check the immigration status of anyone they stop, detain, or arrest anyway? I mean, last time I was stopped they checked my driver's license, which I hope would link to my citizenship. This makes it look more like a political stunt by the republican party than meaningful legislation.
So, is immigration bad for the country? Are Mexicans taking jobs from Americans? Are they getting free health care, free social services, or welfare checks?
Let's look at crime, which is one of the main issues raised.
According to this article by Mariano Castillo the claims made by Senator Russel Pearce could not be backed up by the AZ law enforcement due to lack of statistics. Also, violent crime overall has fallen in AZ for the past two years despite healthy population growth and large numbers of illegal immigrants. If you subtract out the number of immigrants who are arrested solely on immigration related charges, is there still a spike in crime, if there ever was one? By FOX's own admission most of the crimes are caused "by drug traffickers and immigrant smuggling groups", which if immigration was opened up (and marijuana legalized) would both disappear. So it almost looks like the new law (and the existing policies) are actually supporting the crime wave.

But I want to look more at the idea of restrictive immigration to begin with.
I believe that because a person was born within a given area should not determine their allotment of opportunity. For this reason I am opposed to steep limits on immigration. However, I do see that the social ramifications of millions of Mexicans moving into Arizona, Texas and California will drastically strain the resources of those states. Why don't we open up some other states for immigration? Base it on population, and limit the number to what we think those states can reasonably handle? I know that the economy is down right now, and that competition for jobs is fierce, but that isn't only true in America.
If Americans are truly scared of the "threat" of illegal immigration then they must believe the Mexicans can take away their jobs. I'm fairly confident that my employment is safe. I worked hard in school, have a B.S., and am close to a Master's degree. No immigrant is going to take my job anytime soon. Perhaps if Americans spent more time in school, placed a higher value on education, they would feel less threatened. Of course, Americans without skills need to realize that there are plenty of jobs out there, but they are jobs that don't pay very well. These are the jobs that the immigrants are taking. I don't see a long line of Americans looking for a minimum wage (or less) job picking fruit or cleaning my home. This is really a cold-hearted look at the whole thing, from an American's standpoint, but we have become content and lazy, and the very idea that immigration is a big issue for Republicans means, to me they've got all the other issued tackled. Perhaps if they focused more on education, job training and infrastructure then the employment issue wouldn't be a problem.
So, no, I don't think this law in itself is racist, but the policy of persecuting those who come here illegally is not only counter-productive, but it's not in line with a humanist outlook. America's opportunity is what makes this country great. Let's not take that away.
