More than fifty years ago Dr. Martin Luther King Jr. heroically battled segregation and built a coalition of conscience to change our society and its laws. Today, a new struggle is being fought in many of the same places. Arizona, which famously refused to recognize Martin Luther King Day as a holiday, and Alabama, home of the Selma march and Dr. King’s “Letters from a Birmingham Jail,” today defend the most punitive anti-immigrant state laws in the country.
Under the banner of regulating immigration, these laws would institute a new system of discrimination. They would encourage – if not compel – racial and ethnic profiling, prohibit offering transportation and housing to undocumented immigrants, impose state punishment for immigration-registration violations, and – under the Alabama law – require schools to conduct immigration checks on students and their parents in a transparent attempt to deny children their constitutional right to public education. This virtual barricading of Alabama’s public schools by state officials is a grim reminder of earlier refusals to provide equal education for all.
It is telling – and deserves high praise – that the Obama Justice Department has joined Alabama’s religious leaders and a coalition of civil rights groups in suing to stop the Alabama law as it did the earlier Arizona SB1070 statute.
To be sure, immigration is a complex subject. But falling prey to superficial responses that exacerbate discrimination, target all who look or sound “foreign,” and cater to those who fear changing demographics or new immigrants is not the answer. Though sadly, it is nothing new and as much a part of our history as the glorious Statue of Liberty. For example, earlier hostility against Chinese immigrants in California led to racist state and local laws, including the infamous San Francisco anti-Chinese laundry ordinance that was struck down by the Supreme Court in 1886.
But easily overlooked in the current controversy over state anti-immigrant laws is the even more fundamental fact that federal immigration laws and practices routinely deny basic constitutional protections to non-citizens in a system of mass arrest, detention and deportation.
