Saying someone is black should not confer anymore information than saying someone has curly hair. Of course, because of all sorts of cultural considerations, that's not the case. But it's still how the law should view race, i.e. not at all. Male and female are real categories, regardless of what the gyno-American set may think. Gay and straight are real categories too, covering very specific behavior and attitudes that are vastly more significant than skin color.
Marriage is and has been defined as a specific union between one man and one woman.
By saying that marriage can be a union between a man and man, or three men, or fifty, changes that definition. You may think it' s fine or even vital that we change the definition to include same-sex couples, and therein lies a worthy debate. But spare me this haughty and feigned na vet . If you can't tell the difference between a gay marriage and an interracial one you are either a fool or a liar or quite possibly both. Romance and intrigue will play a role, to be sure, but it will most assuredly be a tale of bloodlust and rage.
