Actually there are identifiable factors at play in what we're labeling 'racism' (and maybe it is for a lot of these people who knows) that could have nothing to do with racism.

For instance, it's not at all weird to feel like immunity for illegal immigrants would be unfair given that there is an immigration backlog for even highly skilled foreign workers. When there are millions of people in Africa and Asia who are both more qualified and more in need than the average illegal immigrant from Mexico, it's tantamount to arguing that geographic proximity should imply preferential treatment.

Chances are the legal (voting) Hispanic demographic has reached a sizable enough proportion of the electorate that Dems have decided they're worth annexing with some platform concessions. Slap on a veneer of compassion and all of a sudden it's a part of the progressive agenda. That they got away with it so cleanly and we're no longer questioning the logic of these policies is a demonstration of one way in which the liberal left can be bamboozled as easily as the Tea Partiers.
