I am a professor of human biology at Baruch College, City University of New York. I sometimes get involved in discussions with â€˜gayâ€™ students on issues of biology and homosexuality, but such discussions have always been respectful and educational. For example, a young â€˜gayâ€™ man told me he was opposed to all the hatred directed against â€˜gay marriageâ€™; why couldnâ€™t the government recognize the equality of â€˜gayâ€™ unions? I asked him about the lifespan of nations, compared to the lifespan of individuals. He acknowledged that nations span many generations. I added that, in fact, one of the few real responsibilities of the national government is to ensure that there will be future generations of citizens. Therefore, I said, is it not really the responsibility of the federal government to provide special protection to the very institution that guarantees future generations of citizens, i.e., marriage between a man and a woman? His reply: â€˜That sounds fair.â€™ And he walked out of class satisfied. We all know that youth tend to be possessed of idealism, which is these days so often confused with, and perverted into utopianism. But youthful idealism is really the love of truth, and nothing makes it shine like truth!
