How strange that the president of Mexico, while a guest on the lawn of the White House, would attack the laws of a U.S. state, while his own country’s immigration laws and policies in relation to Central America have never approached American tolerance. It is unimaginable that an American president would ever travel to Mexico City and lecture that nation and its president on its treatment of both aliens from Latin America and American tourists. But, as President Obama reminded us, “we are not defined by our borders” — although apparently a million Mexican nationals a year disagree and so risk everything to be on the north rather than the south side of a supposedly imaginary line. That is the truth that we dare not speak.
