This is an historic opportunity to broaden the American understanding of equality — just as Loving v. Virginia did nearly a half-century ago. And in both occasions, Maryland has stood at the crossroads. In Loving, Maryland was on the wrong side, having been the first colony to ban interracial marriage. This time, it may be the agent of change as the lead plaintiff in the case, Jim Obergefell, wed his late partner John Arthur on the tarmac of Thurgood Marshall Baltimore-Washington International Airport two years ago. It was Ohio's failure to recognize the marriage that caused the couple to file the lawsuit that now must be decided by the nation's highest court.
