When people say things like " find it interesting that Christians are the most outspoken against gay marriage", I automatically take it to mean "of the people against gay marriage, it is the Christians who are the most out-spoken".
This is a little off-topic, but why are people so eager to stick themselves in boxes such as "republic", "democrat" and so on? Personally I think that approach opens the door to people who would rather oppose issues with labels.
(I'll split this off if it gets interesting - now split off to here)
