I think there's tremendous significance and opportunity in Americans seeing legally married gay couples treated with respect in our nation's capital.

Marriage is not defined by who is denied it. When gay people share in the freedom to marry, it doesn't change your marriage.

Marriage is a language of love, equality, and inclusion.

My marriage is my marriage, and it means I'm able to share in the same aspirations of commitment and love and support and dedication and connectedness, and that my parents are able to dance at our wedding and that our family and friends are able to support and celebrate and hold us accountable for the commitment we've made to one another. That takes nothing away from anyone else.

Marriage is also a social statement, preeminently describing and defining a person's relationship and place in society. Marital status, along with what we do for a living, is often one of the first pieces of information we give to others about ourselves. It's so important, in fact, that most married people wear a symbol of their marriage on their hand.

Marriage ... has historically been a battlefield, the site of collisions within and between governments and religions over who should regulate it. But marriage has weathered centuries of skirmishes and change. It has evolved from an institution that was imposed on some people and denied to others, to the loving union of companionship, commitment, and caring between equal partners that we think of today.

I'm not in this just to change the law. It's about changing society. I want gay kids to grow up believing that they can get married, that they can join the Scouts, that they can choose the life they want to live.
