"Zachariah Long (left) and Edward Ritchie protested last year against a gay marriage bill in Maryland. In 1973, Maryland became the <a href=""http://www.npr.org/2013/03/21/174732431/timeline-gay-marriage-in-law-pop-culture-and-the-courts"">first state</a> to define marriage as a union of one man and one woman. Voters there legalized gay marriage in 2012."
