For the record, I was against Proposition 8 in California. I don't think the state should involve itself in what legal arrangements consenting adults make. If two gay people want to get married, that's fine with me.
That said, the people of California voted (again) and they have decided that they don't want the state to acknowledge gay marriage.
Now Google comes along and tries to sue to have this overturned based on the premise that it makes it harder to hire people in those states. This is a nonsense argument but its validity is irrelevant. What is relevant is that a very large corporation is trying to sue to change a law that was expressly voted on by the people.
What's worse is that a powerful, public corporation is getting involved in social politics? How long until such a culture pervades into other parts of their business? Maybe websites that don't have "correct" opinions start to not show up on Google.
I don't like big brother, even when big brother agrees with my politics.
