It is sad that such a big deal is made over this. Aside from the Bible, the only ever argument I hear against gay marriage is that "it is defined as a union between a man and a woman", and redefining this would be a pain in the arse, so don't do it. It is very easy to just call it "A union between two people", gender neutral, easy to understand and vague enough to avoid confusion. It is so pathetic that people take issue with this issue.

I find it disturbing, your OP seems to indicate that an individual's opinion on this issue could enhance, or hamper their chances of making it to the supreme court...as Kittens mentioned, this is at the very least bordering on the unconstitutional. I cannot remember the right wording, but it goes something like "no person should undergo a religious test to hold public office", or words to that effect (if I remember it right), and since much of the opposition is religious, in practice it would be a largly religious test.
