David Quigg over at HuffPost: Save My Marriage From Irrelevance: Reverse Prop 8 

The thought is simply this: While my relationship with my wife is going strong, my marriage has never seemed less important. For all the bigoted blather about how gay people undermine the true meaning of marriage, I — on a totally non-political, human level — feel exactly the opposite. My growing indifference to the institution of marriage grows precisely from my everyday experience in the company of gay and lesbian couples who embody the true meaning of marriage. Denied the right to marry, our friends nonetheless give each other all the care, love, honesty, loyalty, support, shelter, and shared laughter that marriage is all about for me. You can’t spend much time around couples who accomplish all that in their daily unmarried lives without realizing that you don’t need a marriage to love each other well. My marriage begins to seem about as essential as my appendix. Vestigial.
