John Corvino, Wayne State University professor, philosopher and gay-rights activist, debated with Glenn Stanton, author of "Why Marriage Matters: Reasons to Believe in Marriage in Postmodern Society," over the issue of gay marriage at a recent program held at Idaho State University . Corvino said same-sex marriage is a win-win situation. "It doesn't take anything away from heterosexual marriage," he observed. He said society should support all good, solid relationships.
