John Corvino, assistant professor of philosophy at Wayne State University, and Glenn Stanton, a Focus on the Family senior official, continued their long-running debate at Central Michigan University Tuesday evening over the ramifications of same-sex marriage and civil unions. Corvino said that the issue comes down to recognizing that gay people exist in the world and they find happiness in same-sex relationships. Legalizing their unions does not take away from heterosexual marriages and benefits society in the long run, he said. Stanton, Focus on the Family\'s senior marriage and sexuality analyst and director of global insight for cultural and family renewal, said the debate is about the nature of marriage and whether same-sex marriage contributes to \"human well-being" and not about homosexuality.
