Racism from A-Z

For two posts (including this one) now, I have been condemning racists, first people and now a state. Well, not an entire state, just a state congress, Governor and 70 percent of this certain state. I think that all of you 4, sorta, followers know what I'm talking about:
Arizona.
Yes, this Southwestern state, the Grand Canyon state with a population of almost 6 million people, 300,000 or so of which are illegal immigrants.
And this 5% of the population is causing a national stir, you may have heard about this protesting going on all across America, who knows, maybe it was even in your town! (who am I kidding. The only people who have ever read this blog have not only been in one state, not even in one city. In one side of one city in one state in one country. Good ol' west side of Madison, Wisconsin, USA) But anyways, this new immigration bill states that any police officer can ask any person who they suspect of being an illegal immigrant for documentation of their legal status in the country. If they do not happen to have their papers with them, they could be arrested and perhaps even deported no matter if they are or are not an illegal immigrant just because they did not have their papers with them.
This is called "Racism"
There are many excuses to justify this law, one of which being that about 60 percent of the cocaine that enters into this country through Arizona, and another being that Arizona has the 6th most approximated illegal immigrant population in America.
But it's the ladder argument, however is what I use to say that it is, in fact, a racist law.
What I say is yes, Arizona has the 6th most approximated illegal immigration of any state in America. But then, factor this in, Arizona also has the second largest Mexican foreign born population in the United States, 5 times the amount of the Asian foreign born population and 6 times the amount of the European foreign born population, almost 2/3 of the foreign born population was born in Mexico. Why would you target anyone accept the vast majority?
