Gay relationships "are consistent with the core of the history, tradition and practice of marriage in the United States." There is no "historical purpose for excluding same-sex couples from marriage." "Gender no longer forms an essential part of marriage."
These are quotes (not covered by the media that I heard) from U.S. District Court Judge Vaughn R. Walker's ruling on Proposition 8, the words of which simply define the term as it has always been defined.
That ruling, and I have read it all, seems silent on the historical definition of "marriage" and why the people cannot establish the codified definition after all these centuries. He never develops just how the simple words of the constitutional amendment violate any Californian's 14th Amendment rights. He also does not comment on why history and prior judges never recognized this violation before, nor comments on why his expansion of who can marry can still be limited to "couples."
