This should come as little surprise. When a society creates law and policy that reinforce underlying prejudices we often very quickly see this reflected in more open hostility towards people perceived as part of the group.
Of course its a shame that anti-imigrant sentiment has driven politicians of the state of Alabama to do, perhaps, what seems normal in their circles, and create laws that make treating other people like equals impossible or criminal. What generally follows, when one institutionalizes cruelty, is that people become cruel and discriminating towards anything aproximate to the blighted group in question. We're certainly seeing this here.Human decency and fairness take a backseat to policing the overt cultural biases.
UPDATE: Excellent op-ed in the NY Times on the subject here.
And now for some daytripping music. Killer track from Chromatics, "In the City".
