"One perspective, however, keeps coming back at me. Fundamentalists believe that marriage is between a man and a woman and for the purpose of creating a family.
A gay couple is incapable of having their own children, they assert, so they do not qualify to be married. But what of heterosexual couples who marry with no intention of having children. Beyond any issues of infertility of illness, there are men and women who are married in the eyes of the state, enjoying all of the legal benefits, who have no intention of having children. They seek only companionship and all of the entitlements that come with marriage. Sex, joy, partnership, caring. All of that is theirs, even though they will never bear children and willfully so. If the state says they are free to do that, why aren’t gay couples, as well. This country denies gay couples that right only by asserting that gay Americans do not have the exact same rights as those deliberately childless straight couples. And that is to say that homosexuality itsef is illegal.
Opponents would have to say that they do not want gay couples to enjoy the same lifestyle as straight couples who refuse to have children because gay Americans are not entitled to have the sex, joy, partnership and caring that their straight counterparts have.
They would, therefore, have to outlaw homosexuality itself. Either that or outlaw every single marriage wherein that couple refuses to raise a family. One or the other. That’s it. No other choise."
