Isn marriage really about procreation?
Gay and straight people have the same mix of reasons for wanting to marry. For many these include parenting, for many others not. Millions of non-gay married Americans are in non-procreative marriages (think of Bob and Elizabeth Dole, or George and Martha Washington). And many gay men and lesbians do have children, but have been denied the right to raise those children within a marital relationship. Legally and in reality, marriage is best understood as a relationship of emotional and financial interdependence between two people who make a public commitment. Many people wanting to get married—gay or non-gay—wish to be parents; many others do not. The choice belongs to the couple, not the state.
