I'd wager that the average anti-gay marriage voter in the US does not go to the poll for the purpose of voting to oppose gay marriage. They go to vote for an elected office, or because they were told that it's their duty to vote, and then they see a proposition on the ballot and tick whichever box is against gay marriage. They do this without much thought and based primarily on the views of the community they are immersed in. Never attribute to malice that which is adequately explained by stupidity.
