"Preventing lesbians and gays from marrying does not cause more heterosexuals to marry and conceive more children. Likewise, allowing gays and lesbians to marry someone of the same sex will not discourage heterosexuals from marrying a person of the opposite sex. How, then, would allowing same-sex marriages reduce the number of children that heterosexual couples conceive?" - Theodore B. Olson, former Solicitor-General of the United States - under George W. Bush
This procreation argument cannot be taken seriously. We do not inquire whether heterosexual couples intend to bear children, or have the capacity to have children, before we allow them to marry. We permit marriage by the elderly, by prison inmates, and by persons who have no intention of having children. What's more, it is pernicious to think marriage should be limited to heterosexuals because of the state's desire to promote procreation. We would surely not accept as constitutional a ban on marriage if a state were to decide, as China has done, to discourage procreation.
"Science has taught us, even if history has not, that gays and lesbians do not choose to be homosexual any more than the rest of us choose to be heterosexual. To a very large extent, these characteristics are immutable, like being left-handed. And, while our Constitution guarantees the freedom to exercise our individual religious convictions, it equally prohibits us from forcing our beliefs on others. I do not believe that our society can ever live up to the promise of equality, and the fundamental rights to life, liberty, and the pursuit of happiness, until we stop invidious discrimination on the basis of sexual orientation." - Theodore B. Olson, former U.S. Solicitor General of the United States - under George W. Bush
