You aparently don't understand a basic issue here. It was the biggest reason that they were pro-sKerry. They hate this country and all that it stands for. This is a country founded on the Gospel of Jesus Christ, that owes every speck of it's greatness to that fact, thus all that are not of the Lord's elect must oppose us.
Some of them could be Christians or have some religious affiliation, but they apparently must be Anti-American.
