Justice Antonin Scalia says that allowing gays to marry with redefine marriage which has been unaltered for millennia. Fortunately, Justice Ruth Bader Ginsberg was there to remind him that marriage has indeed changed in the last 1000 years.
Here in the U.S. "New York in 1848 was one of the first states to grant women any rights in personal and real property [within in a marriage]." That's right, just 168 years ago, here in the land of the free, all of a woman's personal property INCLUDING ANY CHILDREN became possessions of the husband upon marriage.
Also, until the middle of the 20th century, marriage was forbidden by law between couples of different races in two thirds of the States.
Those are two pretty major changes certainly more recent than 1000 years ago.
Maybe in the hallowed halls of justice it's easier to forget that he no longer owns his wife. Poor Mrs. Scalia.
