A homosexual couple's "marriage" can NEVER result in offspring who share DNA with each member of the couple. A heterosexual couple's "marriage" can, and most often does. Hence, they are not the same relationship.

U.S. health officials are weighing whether to approve trials of a pioneering in vitro fertilization technique using DNA from three people in an attempt to prevent illnesses like muscular dystrophy and respiratory problems. The proposed treatment would allow a woman to have a baby without passing on diseases of the mitochondria, the "powerhouses" that drive cells.
Also, too, I guess Richard Mayhew doesn't have a "real" marriage in your eyes any more?
