This is silly. Nobody is trying to impose anything on anyone. Gays simply want to be able to live their lives in honesty and peace. The only reason it's a big deal is because the evangelical crowd wants everyone to live by the Bible, that is, the parts of the Bible that fit into their worldview. They like to leave things out, like killing disobedient children, sending women out of town when they're on the rag, etc. (Hmmm . . . maybe . . . no, never mind.)
Bill Clinton did more to negatively effect the state of marriage in the US than gays ever could.
