We are not worried because of some mexicans.
We are pissed off because our government passes laws that they dont enforce, creating an illegal minority class in this country. Then they lie to the American people while ignoring the problem until it gets to the point where they declare (due to their incompetence which is never mentioned) that they have to suddenly make millions of people legal, people that broke laws and jumped their place in the immigration line because it now has suddenly become a crisis. A crisis that they created.
It is not about race, it is about government apathy, incompetence, and flat out criminal behavior.
And the releasing of hundreds of criminal immigrants a few days before the sequester is provably a political move rather than a budgetary move. And the white house is running around telling us they had no idea it was happening. Obama doesnt seem to have much control over what happens in his administration.
